I made a queen size a couple of months ago and it weighed 35 lbs and I used Hobbs batting. Was really difficult to manuver around while trying to quilt on my home sewing machine. I am currently working on a t-shirt lap quilt 60x80" and this time I used a thin polyester batting. I also used a lighter weight stabilizer on the back of the t-shirts. Hope this one is easier to quilt!
