I thought I'd give one of those arrowhead tacks a go. I have to admit I haven't done these very often and had to refer to my old Vogue Sewing book, and dig out the embroidery cottons:
And take a long stitch across the bottom:
I changed to a double strand of embroidery cotton here, as it gave a more satiny effect. You keep taking stitches across the apex, and this stitch gets slightly wider as you move down from the point:
Pull the thread through, so it lies flat and the tension is even:
Then stitch across the base - this stitch gets narrower with each round:
And pull the thread through evenly...ok, it's a bit tight here:
Keep going around and around until you are finished - cute eh?
Have you done any arrowhead tacks before - where exactly do you place them? And do you have any sewing tips for neat and tidy arrowheads?
