In the search for more usable scraps I dumped out my crumbs scrap baskets (basically, everything I deem to be too small to be worth saving with the bigger scraps, but still big enough NOT to end up in the stuffing bag). There I found a lot of small triangle cut offs, which I then turned into small (1 1/4 inch) half square triangle blocks. And those HSTs I then turned into pincushions.
First one was from the green scraps basket and turned out 3 x 3 3/4 inches (one of the HSTs is 3/4 of an inch after sewing)
Second one is from the blue basket and has a five by five grid (3 3/4 x 3 3/4 inches)
I'm quite pleased with the results and also that I found something useful to do with those tiny scraps.
