I am making a star quilt using flying geese... I was looking for an easy way to construct the geese and came across this blog

http://blockaday.com/making-your-geese-fly

well, I need 2X3 1/2" width for sky and 2x2" length for the geese to finish 2x3 1/2"

I tried this technique adding 1 1/4 " to the 3 1/2 to = 4 3/4

and 7/8 to 2 to = 2 7/8... it is a great technique, but my geese ended up 1/2 " bigger all the way around, with 1/2" at point instead of 1/4.

Can anyone tell me what I did wrong??? I am pretty frustrated at this point. Thanks. Quilter 1234
