Thought I'd share a few ideas. I certainly loved looking at yours.
I love to applique` so a scrap pile is super for that. The spring quilt is all scraps.
The tote bag I made for my friend was all scraps.
On the book covers you'll notice a few with checkerboards. Have you ever made checkerboards for a quilt and had some left over that you didn't know what to do with? Here's an idea. The yellow and red ones were for some placemats I made but I did not like the colors once I got them on (looked like a circus!) so I ripped them off and used something else on the placemats so I had all these left over and I liked the way they went on the book cover. Better fabric with it. The diagonals came from making diagonal borders or binding.
Klutina quilter - I have really enjoyed viewing your photo's. Love the wall hanging it is so spring like. Lovely colour comb. And the book covers don't they make a good quick gift for someone. Happy quilting. Ally.
