Whew this block is cutting it close. You can't tell because I crop the photo to the finished size, but there is VERY little seam allowance on this one. It's because I made it from a charm square (of Anna Maria Horner's fabulous Small Gathering in Citrus from her Good Folks line). I have at least 1/8 inch on each edge, so it should be ok. I will probably be using Oh Fransson's trick of ironing freezer paper onto the block so I have a 5 inch square when I am sewing the blocks together.
This block does make me smile though. It reminds me of cotton balls, and really, how can you look at that fabric and not smile?
