Recently Steve was kind enough to send us a booklet with the "Rug Buddies" in it. This is a great PDF of some whimsical toys. I read his blog entry and double checked it. It says use standard 2x4 for making these. However that is an error. If you print out the rug buddies they require 2x6 unless you re-size the toys to be smaller.
I contacted John ( actually Cynthia replied as John was out) at toy press to make certain of this and he confirms those toys do require 2x6 not 2x4.
Just thought you would like to know before you pick up a couple of 2x4's. I'm making some today.
