I wouldn't be able to resist that, either! Do you need a sewing machine cover? Or chair pockets? You could use the larger blocks to make a chair cover: a padded one for your shoulders, with inserts for rice socks ~ the the one that hangs off the back of the chair could hold rulers or whatever...
The smaller pieces could become scrap pockets, or sew together and make one of the travel wraps for scissors / rulers / pencils / tools? You gotta show us pics when you decide! :)
