You may want to try addressing info@cuteembroidery.com with that question as she in the site owner/administrator.

Lowercase would be great, wouldn't it? Unfortunately, unless you can see it on the site, it is not (perhaps only yet) available. I agree with Jrob in that dropping a note to info@cuteembroidery.com requesting lowercase letters would be a good idea. It may not result in your getting the letters you want, but it will at least let the site owner know what her members want to see, and maybe we'll all get the lowercase letters in the end. =D
