i'm in the process of making a t-shirt quilt. i'm not using any stabilizer at all. i've simply spray basted the t-shirts to the batting. each block is backed with scrap muslin. since i'm stippling around the motifs, the shirts remain flat.
i'm making it up as i go along, so i have no idea yet what the final layout will be. it'll be a quilt-as-i-go. these are a few of the "blocks" so far.
once the top is cobbled together, i'm going to flip it over and use turkey tracks to fasten the pieced back. the stitches will go through the muslin and batting, but not show on the front.
