I finished my month 1 blocks the other day (posted about it on my blog already :) ). I didn't have any problems with printing the foundation sheets, but then I don't remember checking anything except the sample block! I'm not a very precise piecer - somehow I always have issues with blocks sizes. Although lucky for me, the smaller the block, the better it is! My Dear Jane blocks seem to be right most of the time. Can't wait to see what blocks are coming for next month!
