Hi! Haven't posted on this thread before but I'm doing the "bitty blocks" , too. They are cute, aren't they? At the moment I'm caught up with 20 of each 3" and 15 of each 4" ....do have to make 5 more little houses because it would appear I never learned to count correctly!!! Think I would say it has been challenging, at least for me, since if you do it scrappy it means cutting all the pieces for each one separately. This last one, the little boats, had 8 little pieces for each boat making 160 little pieces for 20 boats.....whew! ..... anxious though for the next one. Are you all sewing each group into rows like was suggested??? So far I've just kept them stacked on top of one another. If you sewed them into rows how did you fold them so that the bazillion little seams didn't get all mashed so that you had to iron them all out later...ugh! Thanks!!!
