My wife made me a digital (marpat copy) camo modified x-kilt. It is my first kilt, and I'm lovin' it. So is she.

My wife is a very good seamstress, and she's certain she is ready for a tartan. We've not been able to find suitable fabric. We're looking for acrylic, but can't find it locally or online.

Is there some other inexpensive fabric that would be suitable?
