I made myself my own version of a pinafore/jumper last night. I used outdoor fabric so it's a heavy weighted material, but it's very comfortable. Because it's outdoor material I didn't need to line it, which made it very fast and easy.
1. I used Cynthia Rowley's pattern #2215 and used the C version for the skirt.
2. I bought about 3 yards of fabric, so using the left over material I thought it would be fun to add straps. They are two inches in width. I have enough material to add a bodice piece if I really wanted a true pinafore, but I went with just the straps for now.
3. I laid out my leftover fabric and I used fusible interfacing on the back of the fabric. It's a light weight interfacing but makes the straps a little bit sturdier, without feeling stiff. (click here) I ironed on the whole 1 yard onto the back of the fabric.
4. I cut two strips at 4 inches in width, each as long as possible so I could really adjust their length and have it fit just right. The interfacing didn't cover the entire strip but I ended up cutting off the excess material anyways, when I figured out how long I needed the straps.
5. After I folded the strips like a hot dog bun, I sewed the raw edges together inside out .
6. I turned them the right side out and ironed the straps so the seam was down the middle on the back-side of the strap. No one wants to see the seam on your straps.
7. I finally pined the straps in place while I had the skirt on. I made my straps cross in back but you could have them anyway you wanted.
8. I slipped my arms out and took off the skirt and sewed my straps onto the hem of my waistband on the inside of the skirt.
I hope you can make your own creative version of my pinafore. I would love to see pictures.
