Your avatar is colorful and caught my attention. Just love the brights with black. Some of my other quilts have those colors.
That DP 9 patch is on my "To Do List", however, I am trying out the DP 4 next.
IMHO the smaller the pieces, the longer it takes to make a quilt, logical is it not & we all know that but we have to try out these blocks. At least that is me. Ask me how I know, LOL.
My last smallish piecing [for me only] was the Bonnie Hunter [quiltville.com] from the Nov/Dec issue of quiltmaker mag called Hot Cross Buns. 1.5" x 2.5" patches & fun. The 'Twisted Sister' in an earlier issue [may never be made again by me] looks really nice. So, if you have the scraps and the inclination, both types of blocks are ever so cute.
I like that motto, too KISS for quilting.
Anyway, I am off to cut out scraps for the DP 4 in big blocks. Just love the Tutorials here on the QB forum. Then, I will play around with the 10 minute block in 10" squares. My 6" blocks came out very fine using the 10 minute block method and the two quilts [charity] are ever so busy. These will not 'picture' well.
Wonderful Quilting to all in 2011.
