This shirt came to me through freecycle - if you don't know about freecycle, check it out at www.freecycle.org . The shirt's not my size or style, and was two seconds from the outgoing freecycle pile. But the princess loved the glitter & bling and claimed the shirt. However, she's a girl's size 6, not a women's 18/20, so the shirt needed some adjustment.
This idea would work for an adult sized skirt also, just get a shirt that fits over your hips. Or make panels from a couple of different shirts....
Step 1: Gather Supplies & Equipment
Pins - normally, I'd use straight pins, but I used safety pins here because I was pinning onto a 6 year old - a species not known its ability to stand still
Marking tool - not shown - I snagged a washable marker from a school backpack, use whatever you have, no special fabric marker required
Straight edge for marking, optional - I used the side of a note pad, you could actually use a ruler if you were inclined to get up and get one from the other room - or you could just mark freehand
Cutting tool - I used a rotary cutter & cutting mat with ruler. You could use scissors. I don't think a box cutter would work well....
Sewing machine & thread OR hand sewing needle & thread
Cost: ummm, zero... got the shirt for free, and already have the sewing machine & supplies
Time: about 20 minutes, most of which was spent pulling out & setting up sewing machine & tools
