My mum gave me a jersey skirt yesterday as she didn't feel comfortable in the colour for herself. It was too big for me to wear as a skirt so I'd originally planned to reduce the waist and wear it as a skirt, but the fabric is quite thin and it just didn't hang very well on me. I found that it was a lot more flattering higher up on the waist, and decided to attach it to a jersey top and turn it into a dress. It now flows and twirls really nicely :)
It was very easy to do, and doesn't really warrant instructions, but I thought I'd share the type of stitches and basic steps that I used. There's probably a much better way of doing this with a sewing machine, but I don't have one, so this is how I did it by hand:
1. The skirt's waistband was orginally constructed from a length of elastic within a fabric tube. I unpicked the stitches that fixed the elastic in place. Then I made an incision along the inside of the waist band and pulled the elastic out slightly, and reduced the length of the elastic by a couple of inches to make the waistband smaller. This created some subtle gathering around the waist.
2. I then put on the t-shirt and pinned the skirt around me at a comfortable height. I took it off and used a tape measure to check that it was the same distance all around.
3. I stitched the very top edge of the waistband to the t-shirt by hand using a small overstitch. To do this, I pinched the two layers together (see above) and sewed in this position, and when the fabric is flattened out the stitches are along the inside of the seam and hardly show. The stitches allow for an amount of stretch needed for taking the dress on and off. (If I had a sewing machine I would have liked to use a zig zag stitch but these stiches would have been more visible than the overstitches.)
4. I turned the whole thing inside out, and sewed the t-shirt to the internal waistband seam using a loose running stitch (see above) so it stays flat and doesn't roll up when it's washed. Then I cut off the excess t-shirt fabric.
