I just used this block to make a quilt!!
A TON of fun, but that last bit about the seams had me -- I ended up ripping a few stiches on every block to get it all to work out.
Also the blocks ended up way smaller than I thought (I didn't see the part that it only makes a 6" block -- would have taken FOREVER to make the whole quilt, so I made a couple of the same block in a 12" size to finish up the quilt fast.
I think using a solid color in the blocks (where the green is in the pattern) could help "calm" down the quilt as well as draw it all together as a cohesive unit.
Here's a pic of my quilt -- if you have any questions I can help with -- just ask.
