I suppose it would work. The whole idea is 1) to stabilize the t-shirt so that it quilts like straight cotton would quilt and 2) not spend a bunch of $ doing it. You don't want it to have much give, or you'll possibly end up with t-shirt stretched out between the cotton sashings, or puckers.
That 'pretty' frost was a pain in the @#$%%@#! It sure caused a lot of trouble around here. Our neighbor had to cut down an 89 year old fir tree in her front yard. The top branches gave out, and as they fell, they broke branches all the way down. There are old trees all over town that have been cut down. We were lucky. The tree shown is an Austree, and I think there was only 1 major branch that broke. That tree will recover. At the farm, we big branches fall, one hitting the house. It's an obstacle course to go into in the house. The tree in the yard was old when Don's grandparents built the house in the 1930's. Grandma spent $1000's 15 years ago to have the tree trimmed so that the branches wouldn't hang over the house. We would have lost the whole has if she hadn't. Some of the branches cut out were 30" across.
