|This is a tip that I received from Shannon Gifford in the "Stitch and Flip Jacket" Class. It worked so well for me that I wanted to share it.
I was having difficulty putting my sleeve into my jacket. I couldn't ease it in evenly--though I was following pattern directions. Little tucks were forming along seam line and I was getting frustrated.
I searched this site and checked some sewing books that I own and didn't find much help.
Here's what Shannon suggested:
"I like to use three rows of basting to ease sleeve caps. Stitch one row on the stitching line, the second row 1/8" to one side of the first line, and the third row 1/8" to the other side of the first line.
Draw up the basting lines until the cap will fit into the armsceye. Then take the sleeve to the ironing board, and press the area that has been eased. Use lots of steam, and let the sleeve cap cool before stitching it into the armsceye.
After you stitch it into the armsceye, remove the basting. There may still be some small dimples, but the sleeve head will fill those out and make them disappear:)"
This procedure caused the seam line to curve appropriately and the sewing went much smoother--not perfect--but MUCH better!
Hope this helps someone else as much as it helped me.
BTW Shannon is a knowledgable and patient teacher...if you have a chance to take a class with her--go for it--you won't regret it.
