Hi all,
I've looked at the blog tutorial from the link above and done some searching at Walmart, Michael's, Target,and Hancock Fabrics and they all have various brands (including June Tailor, which was used in the tutorial) of Inkjet printable Sew-In Fabric Paper. So you do not have to buy the Twill tape or iron on, just print and sew in.
Thanks again for the wonderful info!
