Ok so knits are tough. The test fabric has a fair bit of stretch in it - it feels nothing like our actual wool so that could prove difficult. And its such an heinous fabric I struggle to cope being in the same room as it, let alone use it to learn machining techniques. The binding machine is surprisingly easy to manipulate as with the overlockers. The elastic may have been a total fluke though, it went in first go. I tried again. It was definately a fluke.
