Well...right now I have been lazy and my scraps have grown again..but when I sort them ...I sort them this way
2.5 inch strips...actually as I do a project all of those scraps go in the same basket..so those are always sorted.
Then when I go thru my bin I cut 5 inch squares out of the bigger peices.
I also have a bin for 2.5 inch squares
then every other sized strips gets sorted according to length and I sew those into panels...from those panels I can make several different scrap quilts and it uses them quickly..I also use these panels to make piano keys on my scrap quilts for borders. ( although not traditional keys because they are differnt width strips.)
I somehow always use 5 inch squares for things and also 2.5 inch strips and squares..so it makes sense to me to sort these out.
