Anybody know where I can find at least a 4 inch number 4 shaped cutter? I looked at Wal Mart and Michaels. Have not checked Hobby Lobby or Joann's (if Joann's carries that type of thing??). I'll also order online if I could find one without spending a fortune. The ones on ebay are 3 inch.

I don't know where you can get one, but I've been looking for 4" numbers as well (that are relatively inexpensive). So, just keeping track of your thread. Good luck!

I've not seen any 4" tin number cutters. I have a set of 2 1/2" cutters I bought at my local cake supply. Most likely, you're are gonna hafta order one. There are copper ones available for about $14.

Another option would be to use a template. You didn't say how many you need to make. It's a pain, but less expensive.

You could also make you own cutter:
