Using an old plastic container (mine was from Christmas decorations I purchased) trace around your existing envelope, or just draw whatever size you want.
Then cut out.
From your fabric, cut TWO pieces which are:
- as wide as the envelope plus generous seam allowance, and
- height of two and a half times the envelope plus a seam allowance
- Flip through (and if you're good, you'll press/iron)
- Insert your piece of plastic inner as shown and push down toward pointy end.
- Fold up the flat, open end and stitch a line to seal it (no picture of this single seam)
- Sew a line of topstitching around the whole outside (should be a stereotypical "house" shape at this stage). I zig-zag stitched on the sides just because I have a new machine and I can't help but try out everything.
- Fold down the pointy end over the first seam you sewed (to hide it) and secure the pointy end with a few hand stitches.... or see below to avoid handstitching.
***** Here are two more, made using patterned fabrics from Windham fabrics, named "Little Menagerie" by Melanie Hurlston of Melly and me. One I left "open" by not hand-sewing down the point. And the other one I avoided handstitching by
- just topstitching the pointy end instead of sealing the short end, and
- folding the point down prior to topstitching around the whole outer. This means the point can be lifted a little but it keeps the envelope shape.
Could you make some of these for someone you know?
