Desperate need of help with my moms quilt
 

I have no idea what I am doing.

Each square has sashing matching the dress or shirt of the doll inside, plus the corner stones of various pieces of fabric found throughout the quilt. I am stumped as to how to assemble these. Technically there are 2 different colored sashes between each square.

Instead of looking at it as sashing, can you add the pieces to each square, thinking of it more as each square having a border and then put the blocks together. Adding the short side to the block first and then the long side with the cornerstone. It's really hard to help without pictures. I'd love to help you brainstorm. Sorry you're feeling so frustrated. You can pm me if you'd like.
