Thanks for starting this thread Klassic! I think it's a great idea. I'd not thought about making my own, I have basic sewing skills and a seamstress/tailor for a grandma who'd probably love it if I asked her to help me on a project like that.
Now, you've got me thinking that I need to make a trip to Joann's and pick up some fleece. That would be fun gifts to make for my lesson students :)
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
