This is perhaps the easiest top in the world to make. All you need is a bandana and three pieces of ribbon (or jersey, or decretive cord). I made a bundle of these in various colours to wear over the summer (which, unfortunately, didn't really materialise in the UK), but they can also be worn over a spaghetti top if you want to add an extra layer.
You will need:
Three pieces of 'cord' - one long enough to fit comfortably around your neck and one for each side, long enough to cross over the front of your body (mine worked out to be about 26 inches each).
We begin by folding down one corner of the bandana. Pin this in place and press along the fold.
Leave enough space along the folded edge to insert the drawstring and stitch along the pinned line.
Now we are going to attach the ties to the sides. I decided to use jersey as I always have scraps of T-Shirts left over from other projects. Pin the ties to the wrong side of the bandana and stitch. Tie the exposed end of the 'cord' in a simple knot to prevent fraying.
Take the last piece of 'cord', attach a pin to the end and feed it through the channel created at the top of the bandana. Knot the exposed ends as before and you're done!
