I need a bit of help with my machine. I've got a Brother 950i machine that lets you programme in your own patterns (fairisle, tuck stitch etc rather than actual shaped pattern pieces). You can draw out a pattern on a mylar sheet and then this is fed into the machine. The problem is that I don't have the pen! I don't know what is special about the pen or if I can use a regular permanent marker. I've tried a few black pens but nothing has worked. If anyone can help I'b be really grateful!
