I finally did it!
It's a good thing I went to bed last night instead of starting this block. It wasn't until I was lying in bed this morning that I realized the 'geese' parts of Dutchman's puzzle all had to be a predominant colour and all the other pieces a background colour.
So I made the 5 1/4 pieces out of blues and all the rest out of the yellow.
I really like this new method! Waiting with interest to see what others have to say about it.
