Yea! A topic I might be able to help with!!
I always wear 'hippie' clothes. They're easy to make and I like to feel like I'm walking around in my pj's all the time.
Most of the patchwork hippie clothes don't really use quilt patterns. They're usually just stripes or squares. I've only done a few pieces of clothing using patchwork because I prefer to hand dye old sheets and go for a simpler look.
But anyway... Patchwork clothing....
1) Decide what shape you want to use and cut the pieces. Squares or horizontal stripes are the easiest. Vertical stripes are more difficult because they look funny unless you cut each stripe narrower at the top and wider at the bottom. I've been too lazy to do this yet.
2) Sew your squares or stripes together. Either use a serger or press your seams open to help them lie flat. Be prepared to have to trim lots of threads the first few times you wash your clothes if you don't use a serger.
3) Prepare to cut.
I'll start with a skirt since it's the easiest. You don't need a pattern. I use a yard stick and sidewalk chalk to mark my fabric.
Iron your fabric in half and lay it out on the floor or a table.
Mark fabric as shown and cut two pieces. Add 2.5" to the length for the casing and hem. I don't add any extra for seam allowance.
4) Seam the sides. I press these seams open also if I'm not using my serger
5) Make the draw string. I usually make the draw string 2x my waist. You can use a measuring tape to determine how long you want yours to be. Just tie it loosely around your waist until it hangs the length you want it. Cut a strip 1.5 wide. Sew the length with right sides together. I put the needle on my machine to the far left setting and use the left side of the presser foot for my guide. If you want wider seam allowances you'll have to cut the strip wider. Use a safety pin to turn the tube of fabric right side out and press flat.
6) Make a casing for the drawstring. Press the top edge under 3/8" or serge the edge. Then press 3/4". Mark the center of the front and then mark for button holes as shown.
Practice your button holes on a scrap of fabric first. It's a pain to have to pick out all those stitches if you mess up! I have an automatic button hole maker on my machine so I use a button that is the same width as my drawstring. You'll have to wing it if your machine doesn't have this feature. I place the top edge of the holes almost at the fold. GENTLY open the button holes and then sew the casing down. Thread the drawstring through the holes and tie the ends in knots or add embellishments to finish the raw edges.
7) Hem. Try on the skirt and mark the hem. I like mine to drag the floor so I just turn under the raw edge and sew a 1/2" hem.
This method of making a skirt can also be used for a dress. Here's a picture of a dress I made for my daughter by adding an apron top to the skirt.
Hope that helps. Let me know if you want a tutorial for wide leg pants or apron tops.
