Tie-on Sleeves in Plum Cotton Fabric

You may remember that an ongoing project is the creation of a suite of tie-on sleeves to complement my Italian style gowns. The other day I was bed-ridden and I was trying to work on sewing down the inside of the seams on one of the pairs.

The sleeves are cut out and zigzag stitch put along the cut edges. Then the side seam is machine sewn (or hand-sewn if I have the time and manual dexterity, which I usually don't).

Th idea with the inside seam is to press or finger-press the seam open and flat on the inside and sew it down with tiny invisible stitches so that it doesn't bunch or twist with wear.

I'll admit that I was struggling with the project, so I was pretty satisfied when I was done.

  I put the project down to admire my achievement........ and looked closer.....
Yep, those are two right sleeves!
Of course, I noticed this after the seams had been machined and then hand sewed flat. (Eyeroll.)
