maybe you could cut them down to 5 1/2" & 2 1/2" squares to make something? i can not think of any blocks that use 8" cuts...visit 'Quilter's Cache' and browse the blocks in the 7 1/2" size to find some inspiration= their may be something that catches your eye. around here most 'pre-cuts' are {charms= 5", layer cakes= 10"} so 8" is a little 'different' ...they can always be cut in half both ways to give you (4) 4" squares.....there are lots of patterns that use 4" squares.
