Minimum 12 shirts. If you have at least 12 t-shirts that you never wear but can't bear to part with, then send them to me and I will turn them into a lifetime memory keepsake custom t-shirt quilt. You can choose your backing color or tell me your favorite colors and I'll pick fabrics to coordinate). I use warm & white/natural cotton batting and white or cream muslin for the backing or you pick the backing fabric. (The one pictured has flannel backing) I will stabilize each shirt for extra durability. It will generally take 4 weeks to make these quilts (or less depending upon the time of year) once I receive your t-shirts. (Customer is responsible for all shipping charges. Refunds will be given to reflect actual shipping charges if necessary.) **After purchase You will be contacted to provide a mailing address for your shirts. *Quilts shown in photos are samples of ones I have done for others. They are not for sale.
