Jersey Girl

I'm still tweaking M6078. This is moving slower than expected. The culprit is the Vera Wang jersey I'm using for the muslin (best Fabric Mart Deal ever. I wish I'd bought more for muslin.) This is my first time working with a slippery, thin fabric. It's all over the place, even with my machine's integrated walking foot. It shifts even when I pin every 1/4 inch.

So, I have questions for you who know what you're doing :-)

• How do I keep the fabric from moving so much?

Look at the pleats:

• What stitch do I use for sewing the pleats? I'm using a tiny zig zag. Should I be using a straight stitch? If so, do I need to stretch the fabric as I sew?
• Is my tension too high?
• Should I switch to a fine or silk thread?

Also, my 2nd-favorite Chicagoland Hancock store is closing. All patterns, except Kwik Sew, were $.99! I didn't do too badly LOL. I stuck to my resolution and didn't buy any fabric. Although, if the matte jersey or ponteroma gets any cheaper, y'all will need to pray for my strength.
