I spent a whole day going thru you tube videos to find decent ones on T-shirt quilt making so I would have something to tell my customers to watch. Most are absolute junk and some even seemed dangerous! But, a very basic one with lots of variations and simple instructions is our old standard - Eleanor Burns Quilt in a Day. Her YouTube video has all the basic info and also how to utilize different sizes (pocket logos, sleeve logos). You do have more than her normal amount of silly talk, but she puts in an awful lot of good instruction in the video.
