Friends, after a 4 month hiatus I can quilt again! I am making a t-shirt quilt and would like to know, if you have made one, what weight of pellon interfacing did you use to stablize the t-shirts? Your suggests are appreciated.

You can find light weight fusible interfacing in most fabric stores... the lighter the better, it is just to stablize the fabric, but you don't want the fused fabrics to be much heavier than the cotton you are using with it :D:D:D

I was wondering if there are alternatives to fusible, to avoid the extra cost?

I thought about using basting spray and attaching the tshirt to another piece of fabric (maybe from some other old shirts). what do you all think?

To stabilize t-shirt fabric, most people prefer fusible tricot. It is cheaper purchased as yardage from a drapery company. I bought mine online from this company:

JoAnn's carries it also.

The idea of using basting spray with foundation fabric is really interesting, but haven't heard of anyone trying that. An alternative might be to heavily starch the t-shirt fabric (1:1 solution of Sta-Flo liquid laundry starch and water) before cutting, but again I haven't tried that. I use the starch to stabilize background fabric for machine applique, but haven't tried it on t-shirt fabric.

If you are going to all the labor and love to make this t-shirt quilt I would splurge and get the fusible. You will not be happy with the starching or attaching to another fabric....

I use a lightweight non-woven fusible interfacing. Love the results!

Thank you all for your suggestions. I will use the lightweight fusible.
