Routine reminders: Seams should be 1/4 inch or a scant 1/4, this includes all the diagonals which is where I most often see the narrowest and the widest seams. Please make sure you are using at least 12 stitches per inch if you are machine sewing. Blocks are to be 12 1/2 inches square - or as reasonably close as you can get them - so measure, measure, measure!
Thanks!
