My fabric scraps are sorted to color and in boxes that are about 9" x 10" x 15" and most of them are nearly full. The red one was at about 3/4 and I just watched an episode on The Quilt Show on making 'slab' quilts. This technique has been perfected by a woman from Calgary, Alberta. Her name is Cheryl Arkison and she has three books out. The video on TQS was fun to watch and making these improv blocks is so relaxing.
What amazes me is that with a few scraps, I already have 15 large blocks (12.5") and will have at least 15 more, just in the reds and reddish scraps from that bin! There are variations in prints, tonal values, etc. but all red and shades thereof. Here is a picture of the blocks so far. To the left is a pile of larger pieces that will finish up 15 more slabs that are already partly sewn.
