Icosahedron dice bag pattern

There are infinitely many non- similar shapes of icosahedra, some of them being more symmetrical than others. The best known is the convexnon- stellated regular icosahedron —one of the Platonic solids —whose faces are 20 equilateral triangles. There are two objects, one convex and one nonconvex, that can both be called regular icosahedra. Each has 30 edges and 20 equilateral triangle faces with five meeting at each of its twelve vertices.

Both have icosahedral symmetry. The term "regular icosahedron" generally refers to the convex variety, while the nonconvex form is called a great icosahedron.

The great icosahedron is one of the four regular star Kepler-Poinsot polyhedra. Like the convex form, it also has 20 equilateral triangle faces, but its vertex figure is a pentagram rather than a pentagon, leading to geometrically intersecting faces.

The intersections of the triangles do not represent new edges. Stellation is the process of extending the faces or edges of a polyhedron until they meet to form a new polyhedron.

It is done symmetrically so that the resulting figure retains the overall symmetry of the parent figure. Of these, many have a single face in each of the 20 face planes and so are also icosahedra. The great icosahedron is among them. Other stellations have more than one face in each plane or form compounds of simpler polyhedra.

These are not strictly icosahedra, although they are often referred to as such. A regular icosahedron can be distorted or marked up as a lower pyritohedral symmetry, [2] and is called a snub octahedronsnub tetratetrahedronsnub tetrahedronand pseudo-icosahedron. This can be seen as an alternated truncated octahedron. If all the triangles are equilateralthe symmetry can also be distinguished by colouring the 8 and 12 triangle sets differently. These lower symmetries allow geometric distortions from 20 equilateral triangular faces, instead having 8 equilateral triangles and 12 congruent isosceles triangles.

The coordinates of the 12 vertices can be defined by the vectors defined by all the possible cyclic permutations and sign-flips of coordinates of the form 2, 1, 0. These coordinates represent the truncated octahedron with alternated vertices deleted. In Jessen's icosahedron, sometimes called Jessen's orthogonal icosahedronthe 12 isosceles faces are arranged differently so that the figure is non-convex and has right dihedral angles.

It is scissors congruent to a cube, meaning that it can be sliced into smaller polyhedral pieces that can be rearranged to form a solid cube. The rhombic icosahedron is a zonohedron made up of 20 congruent rhombs. It can be derived from the rhombic triacontahedron by removing 10 middle faces. Even though all the faces are congruent, the rhombic icosahedron is not face-transitive.

Several Johnson solids are icosahedra: [3]. From Wikipedia, the free encyclopedia. Polyhedron with 20 faces.I have a confession to make. I collect dice. Lots of them. They are pretty and sparkly and feel so good in your hand. I am a dice addict. I have so many dice that they do not all fit in my dice bag. Well, I guess that means I have to make more dice bags! I made my first dice bag over 30 years ago.

The pattern I use has changed over time, but I finally settled on this one as the best. It holds just the right amount of dice. Plenty of dice to play with while gaming without holding so many dice that others want to borrow them. Yes, I am that sneaky when it comes to my precious. When Carl played 3. This bag is in memory of that dear Tressym.

The perfect fabric was sitting in my big bin of someday fabrics! Print out the pattern pieces in this pdf. You will be making two little bags and then sewing them together and adding a ribbon drawstring.

Cut out the two pattern pieces from the paper. Cut out two copies of the dice bag side out of main fabric and two copies out of lining fabric. Cut out one copy of the round bottom out of the main fabric and one of the lining. Iron the pieces. If one the main fabric or lining material is easily frayed as this winged cat fabric is, zigzag the edge or use fray check on the side edges.

This is to prevent it from fraying near the ribbon opening when the ribbon rubs on it. This metallic fabric was so frayable I both zigzagged it and fray checked it. Sew the main fabric, right sides together, along the two sides.

Leave small openings which will be used later for the ribbon drawstring. Do not forget to leave these openings or you will have to use your seam ripper to open it up later. I mark the openings with double pins so I know where to stop sewing. Sew the lining fabric, right sides together, along its side, leaving a gap on one side for turning the bag later.

Take your time on this next step. Sew the side pieces of the main fabric to the bottom of the bag. Make sure you arrange it so the gaps on the main fabric sides are near the TOP of the bag.My husband and I have recently started playing Dungeons and Dragons with a group of friends. We have been having lots of fun on our fantasy filled adventures.

My husband asked me if I could make some sort of drawstring bag for his dice. I went into my own dungeon of crafts and in about an hour I came back with this pretty awesome dice bag. The others in our group were pretty jealous but I plan on making them all their own pouches. Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. Now its time to measure and cut your pieces. This bag can be customized to just about any size. Here are the dimensions that I used.

Now its the fun part, seeing your bag actually take shape! Take the exterior bag body and fold it in half. Take some chalk and mark an inch from the top edge. Make another mark a half inch below the first mark.

Next pin the bag and sew! Sew until you come to the first chalk mark and cut, then continue at the second chalk mark. This little hold is going to be where we insert the drawstring.

Take the lining body piece, fold in half then sew. To both exterior and lining attach the circle to the bottom. Note for the exterior the bottom is the opposite side of where the drawstring hole is! Keep lining inside out. Place the exterior inside of the lining. Pin along the top edge, leave about two inches open and sew. Pull the bag inside out through the two inche hole. If its stiff you can iron it out a bit to make it nice and crisp. Pin up that little two inch hold and fold the raw edges so they are hidden.

Sew a top stitch along the top edge. Next find the drawstring hole, pin along the bottom hole and sew around again. Take a safety pin and attach to one edge of the string. Locate the drawstring hole on your bag and feed the string through to the other side. When it comes out the other side you can take of the safety pin and knot both endes of the string. For a 5-inch diameter circle base, you'll need a rectangle that's a little over Also, what seam allowance did you use?Eventually I came around to the idea of making some dice bags!

Of course, you could use these for loads more besides dice. They make a great accessory for anyone into Renaissance fairs or for holding special trinkets. Sssooooo I tried this, and my sewing machine did not like the leather and i did buy leather needles specifically for this any advice? Is the needle not piercing the material? Or is the machine not moving the material when you sew? You are commenting using your WordPress. You are commenting using your Google account.

The tiny one is just over three inches tall, and holds little things for you. The larger size is about five inches tall and will fit your phone, wallet and keys along with your dice. There are a deceptively large number of parts to cut out, which is one of the main reasons that a kit makes sense here.

Our kit includes twenty canvas pieces, twenty iron-on stiffener triangles, twenty cotton liner pieces, a cord for the handle, a zipper, and iron-on numbers in the lovely font BPreplay. Assembly takes a few hours and requires thread, needle, scissors, pins and an iron for fabric, not solder.

A sewing machine will make some parts go faster. There are two sizes of iron-on stiffener panels: little ones eight of these and bigger ones twelve of these. The little ones are to allow clearance for the zipper. The standard allowance the sides of the triangles is about a quarter inch for the tiny bag and about three-eighths for the handbag.

The smaller stiffeners that go next to the zippers have the same allowance on the two regular sides, and an additional quarter inch on the zipper side. Place the stiffener with the plasticky side may be very smooth like the back of the numbers or may be rough but have a distinctly plastic texture against the canvas, and place a hot dry iron on the canvas side for seconds. Arrange your numbers and fuse them under the iron for seconds. The first set of pieces to sew together are the ten that form the band around the center of the bag.

Bag of Dice Holding

There will also be five pieces on the bottom and five pieces for the lid. If sewing by machine, your zipper foot will help guide the stiffeners along. The next thing is to sew the bottom five panels on. Lay them over the sewn strip on the non-zipper edgeoverlapping the edges and sew straight across the whole batch.

D & D Dice Bag

Follow the same pattern as for the bag body. Once you have both done, it will be time to pin the zipper in place between the canvas and the liner. The zipper should be aligned fairly deeply so that the seam goes just below the intersection of the triangles. Pin across the zipper and sew it in place. Once the zipper is in place, close it and mark the triangle intersections with pins on the lid side of the zipper.

Pin the zipper edge pieces for the lid to the zipper with four more of the loose liner pieces. Sew the zipper on and test it to make sure it can freely open and close. Next, begin sewing the lid together.

Start at the open end and sew toward the intersection at the zipper edge. Sew the last lid piece in and attach it to the main body of the bag with the cord placed between the pieces.Find the best free crochet bag patterns including crochet purses, crochet totes, gift bags and more.
