Thanks for all the comments on my monster t-shirt quilt all! The fact is, I did quilt it on my regular home machine and it was a beast to do. I had to put chairs all around to help support the 10# wt. of the quilt. I did the 1/4" outline for the most part, as I had already done the quilting for the individual tshirt blocks before I sewed them together. So really all I had to do was quilt the sashing and borders.
Mostly I used the puddle technique, along with rolling the part that was in the throat. It helped a lot that I didn't use batting, as the t-shirt squares were already double layered and I used flannel on the back. The recipient lives in California so they really didn't need a "winter heavy" quilt.
