The background center is a rectangle w/ the corners sewn to them in different sizes similar to the snowball, or flying geese. The body is the same a large rectangle w/ two corners (the bottom ones) sewn two them. The comb and beak are the same rectangles w/ one corner sewn, the head and tail are just two rectangles sewn together. (the easy way is not cutting triangles but squares placing them on the edges sewing at center diagonally across the square pressing it then trimming the two back triangle edges leaving the top one.)
I do not know how to do the triangles in the tail and head, but suspect a square that is folded on one side and seamed then refolded and pressed so the seam is to the back and it forms a triangle, they are made then just placed in the straight seam of the two rectangles.
Then it's just adding borders of the background to get the right size.
Hope that makes sense.
I can see the rectangles and triangles, I just can't see how the odd shaped pieces go together, like the beak, comb, the center piece with the back triangles. I'm one who has to see it or have good instructions. I understand about the squares, sewing them diagonally, but I lost you from the pressing part. My Dh picked a large container of strawberries from our patch last evening, so I have to make freezer jam this afternoon. I'm going to try to make one of each, this one and the one I designed and go with the easiest one. Will get back with you this evening! Thank you!
