What's cuter than a platonic solid? A cat dressed up as a platonic solid for Halloween!
This instructable details the making of a soft quilted tetrahedron costume for the more patient of my two cats.
Step 1: Choose Fabrics and Preprocess Them
The first step in any quilt is to pick out fabrics. You will need at least 4 colors, two for the contrasting triangles, one for the outside border, and one for the backing. I was working with fabric scraps from other quilts, so I used more colors but whatever you've got will work. Be sure to wash, dry, and iron all fabrics at least once before you start working with them. There's nothing worse than finding a finished product ruined in the wash by runny dyes or fabric shrinkage.
You'll also need an attractive color of quilt binding. Binding can be purchased at most fabric stores (I use Joanne's). The binding is a cloth strip that will sandwich the outer hem to create a finished edge. Also make sure you have a color of thread that matches your fabrics.
