So I buckled down and sewed three mostly completed sections together. And guess what? It wasn't so bad! I'm not sure why I've been putting this off.
Those tiny tree trunks are on a 4 3/4 block. When I trimmed them, I lost a tiny bit of root. And then when they are sewn together they lost a bit more.
My solution, paint those roots back in with a permanent market. Bet you didn't notice in the first picture.
Take care and have a wonderful day!
