Get a 1/4 inch cording foot for your sewing machine. Makes creating the cording soooooo much easier.
Avoid pins altogether. Seriously. I found using the bull-dob clips made things easier. I didn’t stab myself repeatedly. Once you get the interfacing on everything is so structured that you really don’t need them to keep things in place.
This pattern uses a LOT of thread. I had to go back to my sewing store 4 times. In the end they ran out of my color and I had to substitute with another for all of the interior. It took me 6 spools of coats heavy duty.
Have spare needles on hand and don’t be embarrassed to wear eye protection. You will break needles even if you buy the heavy duty ones. Have a spare packet on hand so you don’t have to put your project on hold while you source some more. At one point I broke one so badly it cut me above my eyebrow.
Congratulate yourself frequently once your finished. If you have been successful you deserve it.
