Thread: stack n whack{making smaller?}

I realy want to make a obw cubed but thought I should do up this ufo first.
Off to the lqs with my 25% shop hop coupon. I found this beautiful butterfly but thought it was a little to dark but its growing on me. It better as it was 16.95 reg {canada}
Anyway I would like to make some lighter smaller blocks the same. Guess their called windmill.
Does anyone have measurments for small blocks.
Thanks Gale
