I did the Mason Dixon baby kimono. It's dead easy. Basically knit in one piece and sew up side and sleeve seams.
You cast on 40 sts for the back, increase for the sleeves then decrease sleeves and increase fronts to get the cross over effect. With me?
If you look at some of these pictures you'll see that at the bottom of the front there's a straight bit before the cast off edge. However on mine, by the time I'd increased enough (back to 40 sts, same as back) I was at the bottom edge already. Still with me??!?
Now I did mine in Debbie Bliss Cotton DK (which I feel is on the thick side for a DK), 4mm needles and stocking stitch with a 5 row garter stitch border.
I'd like to do another one and get more of a straight run at the bottom. What should I change to achieve this?
Yarn?
Garter stitch all the way instead of stocking?
Knit up back more before increasing for sleeves?
