Over the last few days, I did all the tedious finishing details on Mountain Man's situpon.
I decided I didn't like the original cast-on edge ...
So I carefully unpicked the long-tail cast-on, picked up the live stitches, and bound off again, with some k2togs along the way to tighten up the edge. Much cleaner and tidier.
Next, I cut a square of wood grain oilcloth and went around the edges with my small hole-punch. You can sew right through oilcloth with a sharp needle, but holes are necessary for either blanket-stitching with a tapestry needle or crocheting.
Finally, I crocheted the backing to the situpon using contrasting dark brown yarn (actually, the same yarn for Mountain Man's sweater). I did it in a way that looks just like blanket stitch but was much easier (since with regular sewing, I would have needed to be drawing a long length of yarn through each hole, and with crocheting it's just a tiny loop to pull through).
And now it's a sat-upon! We took both sit-upons out climbing yesterday and were very happy indeed on the rough rocks.
Isis feels a bit left out, though, can't you tell?
