The rest of the One Way Street pattern is good, and if your hand isn't really large, will probably work.  

If you (or anyone) wants the instructions and dimensions of each piece from the pattern I made I will post them. Let me know.

Why not try selling a few of your puppets and use the profits to buy more supplies and patterns?  My children both clown and when they were teens they worked as clowns (tying balloons) at Cici's pizza on Family Night.  Cici's paid them and allowed them to set out a tip jar.  They could also hand out business cards (for parties and stuff).  They took all the money they made and invested it in more clown and children's ministry supplies.
Just a thought. If your local places require you to be 16, find someone who is 16 or older to work with you (my daughter often had a younger friend work with her and split the money).  The checks from Cicis will be made to them, and you can split it, or take your half from the tips.
