I just did a deer panel (4 deer, 1 bear, 1 duck, 1 etc). The first thing I had. To do was make them. All the. Same size.18x20 could be 24x24. That is divisible by 2. You could use that in the center and the other 4 blocks on each corner. I used flying geese and bear paws. I would take a picture but it is at the LA. I forgot to say that I bordered the block with black and then cut it down to the proper size. Good luck. With your pattern.
