Hi there.
I've made quite a few of these over the years. In fact I'll be making another sometime over the next couple of weeks for an idea I have.
What I do smooth the end with a file to get rid of sharp edges, then bend (fold) a tiny bit at the end of the wire back on its self with pliers and press it flat. This ensures that, in use, the part that rises has no chance of ever poking through the fabric. Its also much easier to insert as it doesn't catch.
