As I said in the trip report, punchneedling with ribbon is harder (at least for me) than it looks. The good news is that it's easy to pull out the ribbon and after ironing, re-punch; the bad news is that although the second or maybe third go around was better, there were still loops that either disappeared or grew longer than they should be.
After gently nudging most of the distorted loops into shape, I decided that I wouldn't use the punch needle for the third and final color. Instead, I'm using a chenille needle and making ribbon loops. When I'm off the meds, I'll practise, practise, practise the right way.
Have you ever 'cheated' -- taken a short cut, said what the hey, no one will notice if I don't switch colors, etc., etc.
