Latest block completed from the series, name of the block is Windmill,
other names are Dutch windmill, Turnstile or Double Pinwheel
The red fabric provided by the magazine is very thick and the center created a lump in the seams, even though its is as flat as can be. So I made the block again with my fabric stash and this time it was flatter,
a pattern can be found here
and a wonderful how-to blog entry here
