Yup, I recived the instructions and with them, the bag takes about 5 minutes to make. Very nice. Apparently, according to the rep, the fabric store SHOULD provide the instructions with the interfacing. (Thanks once again Richland Center fabric store for crappy customer service!)
I would be happy to share the instructions, but not sure how to get them online. If anyone wants them, private message me. I am sure I could mail you a photocopy.
