Step 1: Plan
Keep in mind that you don't have to do girls in skirts. I thought about doing a guy with a long trench coat, but I didn't have appropriate fabric on hand.
Decide where you want each of your characters to be placed and what sorts of details you want to add.
Don't forget to think about the story. What kind of story can you tell with the characters you've chosen.
Step 2: Gather Supplies
basic sewing tools (scissors, sewing machine, needles, etc.)
red acrylic paint
course bristle brush
Step 3: Patterns
* Remember that you need to make everything a 1/4 in. thicker for seam allowance.
* Make sure that your body, arms, and hair will fit within the length of the skirt. (After I add long hair one side, I'll have to lengthen the skirt.)
* When drawing the skirt, use a ruler to make sure it is the same length all the way around.
Step 4: Faces
* Add all the details to the faces before sewing them together
I'm mostly going to allow the images to speak for themselves for the details. None of these details need to be done the way I did them. Be creative. Use what you have on hand. For instance, I used buttons for the eyes, but you could just as easily use fabric or beads.
