You'll have to try the new block coming out. It is a Wings block and if you look at my avatar you will see curves but they are an optical illusion. There are no curves in this block! But it looks like there are in a lot of the designs.
As for the Drunkard's path I don't do any more curves than sewing a yoyo onto a background fabric with my sewing machine. Then cut in 4 pieces. So easy!! The only hard part is sewing slowly around the circle of the yoyo. And that isn't hard once you get a feel for sewing slowly and turning it as you go.
I do not do curves!! I tried once to do the Drunkard's Path the old fashioned way and curves and I do not get along!! That is why I was so excited when I figured out the way I do it now. I took Eleanor Burns ideas and changed them some added my spin to hers and got what I do now. It is so much fun to see the designs emerge!!
