I too am interested in using up "orphan" blocks. Thanks for opening this thread.
A friend made the little chicken pin cushion for me, and I love it! It is so cute. I use it to hold just needles - mostly for hand sewing.
Another idea I've used is to make a little framed sign for my sewingroom door. I have an "arty" type block with a beaded dragonfly on it that I wanted to do something with that I would see all the time and enjoy, but would not be handled as it is a bit delicate. Hope this helps. Dianna in ID
