I was just going to comment that the block isn't really that hard you just have to remain focused! Argh! My brain is hurting from all the thinking! It must be good for us though. Alzheimer's prevention? Most likely!
I was certain I'd made my first flying geese block wrong but when I read more I discovered, happily, that it was right. Whew! More to do. Hoping to finish before this evening. Hoping!!!
