I do have a walking foot and a Teflon foot, not tried either of those. It isn't bunching or anything like that.
The needle looks odd when its sewing, the thread sort of loops up round the needle, and then when you stop it all pulls out.
Its not leaving any holes that I can see, and the faux suede is on a knit base of some sort with extra loft to the fibres which gives the suede effect.
I had a look at the cardigan construction and I could do that solely on the overlocker, so I might well do that.
The skirt has a back split and a waistband so don't think that's work great on the overlocker.
