Nicely done, perfect fabric choices! I would finish with something simple so that the turkey stands on its own. Rather than blocks, I would simply add whatever length of fabric to each end to get the length you need. Possibly something like the 10-minute table runner. You can find several tutorials for that on Pinterest, including one that shows it with strip tube squares in the focus/center. Replace that with your turkey, centered on length needed, and adjust width (I think it usually starts with a 10 or 12 inch center strip and an 18 inch backing/border fabric - so if your turkey is 16", you'd probably need a 24" backing border).
