Thank you all for the encouragement and kind words.
The green one does not reach 12 1/2 inches top to bottom.
The red one and the third one I made after posting this I forgot the blue corners on the body of the train.
How do I square up the blocks, I have not learned this yet?
I have 12 of the block pieces precut so I will work on putting those together. I think I am going to have 5 train pieces together for 60 inches, 4 rows of trains will a three rows of trees in between the trains. 80 inches in length, or somewhere extimating.
It took me about an hour and 45 minutes to sew one together so it is probably going to be slow moving. I can't wait to see it together either.
Thanks again!! Kyia
