Hey Usonian, as a matter of experience I just ran my newly created Rev. K X-Kilt through its first wash and dry with other clothes (and yes it sat in the dryer for awhile after the dryer shut off). Mine is 100% Cotton Duck cloth canvas and when it came out I started in with an iron and it took me about 30 minutes to get it all sorted back out. Ironing both sides was needed but overall I did not notice any significant puckering around or next to the stitches that would have alarmed me. I did pre-wash the fabric on hot, dried it completely in the dryer and ironed it well with the help of a water spray bottle to get almost all of the wrinkles out prior to making the kilt. Overall it wasn't too bad of an experience and I think it will get better as I become more accustomed to it. Thanks for the post and the information it generated. It was good for my benefit as well.
