I know what you mean, I just finished block three today.
That one wasn't a lot of fun to do.
I really enjoyed block 4 but block 3 wasn't nearly as hard as I'd thought it would be which was a really nice surprise. I'm looking forward to your pictures!
Sometimes I feel just like that too. Don't give up on #3. It is a pretty block and you don't need to do those squiggly finger bits as tight as the pattern. You can still get the same effect if you loosen the curves up a little. Good luck.
Sounds like we can all relate easily..block #2 and all the leaves the same was the one I struggled with so far...it is nice to have some variety!
