i did this a couple years ago- put those unfinished items/orphan blocks/ufo quilts into boxes & sent them to a group of new sewer/quilters who very much appreciated them- it freed me up- i no longer had to feel guilty about not finishing them & the (new owners) were thrilled to have them to work on...i always say- if you don't want it- pass it on- there is always someone who appreciates it- when we no longer do.
