Do you add stabilizer to the fabric sashing also? I would think that the difference in weight of the t-shirt plus stabilizer and the sashing would be too different if not.

Thank you for the replies. I have made a t-shirt quilt before and yes it is time consuming getting shirts ready. I just was not sure what to charge this lady for making the quilt.

No I do not put the stabilizer on the sashing fabric.

AubreyB thank you for the information.
