I've been saving up triangles from when I trim the corners of snowball blocks and other HSTs. They are all different sizes and fabrics. I'm going to start with those and then delve into my 5" squares that I cut from extra fabric. It's going to be scrappy! And I'm looking forward to seeing how lots of different sizes go together. I know I can always put a border around smaller ones to bring it to a specific size, but I'm going to try and do without that. I'm going to vary sizes from other materials so that the 5" square HSTs don't overwhelm the quilt. This is going to be FUN!
