The last two days I have been working on another Archer shirt (made here and two here). This time is a plaid flannel from Mood Fabrics:
I wanted to share with you a tip I learned many years ago at a workshop by Louise Cutting. She uses Steam-a-Seam to hold certain areas in place. For instance, on the front button band, when you turn under the seam allowance, place 1/4" steam-a-seam under this seam. Then press in place. Now the front band stays in place and you can topstitch without any worries.
I use Steam-A-Seam in the front band, collar band, cuffs, anywhere I want to hold the seam before I edgestitch or topstitch.
Check out a tutorial at Louise Cutting's site to see more and photos to help explain.
Here is a photo of the Steam-a-Seam I use
It is on a roll with a paper backing on one side.
