My apologies for being late to the thread, I just registered today.
I looked for some alphabet decals about a month ago in a specific font and couldn't find them. I plan on using this service to get what I need:http://decals4artists.com/index.html
You create a color 300dpi Photoshop file, 10in x 15.5in, and upload it to their site. They print the color decal and mail it to you. It's $40 for one sheet.
If you're fusing a lot of small items like I am, this is a nice deal. The hard part is creating the Photoshop file because I don't want to waste any space and get as much as I can in the 10in x 15.5in area. It's going to take me a while to get my file finished.
There are different qualities of decals and since I haven't used the service, yet, I can't actually recommend them. When I get my final image complete and get my decal sheet, I'll let you know how it went.
Good luck with the project.
