Well I got some pinking shears for Christmas from mother to cut a nice crinkling edge, and I'm finally getting round to using them.. As far as I know the only thing you need them for is bunting which, coincidentally, I love so Bunting it had to be.
Very simple to make it requires pinking shears*, fabric, a triangular template**, ribbon or string, and a sewing machine***. I held the triangular template onto the fabric and used the pinking shears to cut them out, they may not be perfect but that's part of the home made charm. For a more polish look you would draw around the template onto the fabric before cutting. I used four different fabrics and cut four bunts of each one- although I used a random pattern so I didn't use all my pieces.
Then arrange the bunts in the order you want, and pin them on the ribbon/string. I used a nice red ribbon I picked up for £1, and I pinned the triangles to the back of it, then I sewed them. And that was that.
*They're expensive as scissors go, I think mine came in at £10 but that's a cheapish pair. You could just cut straight using regular scissors but that would be sad.
**A triangle cut out of cardboard, my advice is to start with a rectangle, fold in half then cut off the corners to make it even.
***Hand sewing is for suckers...suckers with lots of time on their hands...
