Hi All, I have a ELNA su but I find it very difficult to sew trough 10mm eva50 3mm 3d with xpac + webbing. Maybe I'm just asking to much of the sewing machine. I'm tried jeans needles, microtex and universal. I have some ball points on the way. I've used different threads form guterman. But still no luck I get missed stitches a Lot. I was just wondering if maybe some has an elna su too or have used one and maybe has some tips I'm considering a "new" machine otherwise. A singer 201 if I can get one. (in the Netherlands they cost between 300-400€ ) saw on ebay some in the uk but don't know if they ship it to me. Or maybe an industrial machine. Any tips are greatly appreciated!
