Step 2 Cut triangles and piece them together

Using a rolling cutter, measure and cut equilateral triangles from the chosen fabrics (the size will vary depending on the size of your cat). You will need 9 of one color and three of the other. Pin the triangles together one pair at a time, sew, and iron the seams flat immediately. Never skip the pinning or ironing steps! Quilting is all about patience; you will get far far better results if you are methodical.

Measure a strip of your 3rd contrasting fabric for the outside edge; the border shown in the pictures is a 2" strip. When the 4 triangles are sewn together and ironed into a bigger triangle, pin the border on the edge and sew in place. Once one edge is attached, cut the edges flush, iron flat, then repeat for the other edges.
