Today I am working on a solid black undershirt for this jacket. I am piping the edges there too. It may be too much but I don't have to wear these items together.
This little ruler is a big help when I insert piping. I cut the fabric - here silk tafeta - along the bias, 2 inches wide, stitch the rat tail into a groove using a grooved foot on my machine. Then I use the ruler to trim to 5/8 or 1/4. It has a slot on each side - one for each SA. Pretty slick, huh?
The last two days have been great for staying inside and looking outside here in the southeastern US.
It was still coming down here. Now it's a blanket of white. Lovely if you are not stuck in it.
