I got the f600 in the end :-) she's lovely! Although she is a lot bigger than the cheap singer I was using before! I get a bit of a shock whenever I look into the sewing room!
I've only had time to have a little play so far, there are so many stitches I need to try! I did a bit of fmq on a practice sandwich, which came out really nicely compared to the old machine!
I think the excitement of getting it has caused a flare up of my cfs/me which is why I haven't had a real good play on it. It's a shame but I've got all the time in the world to get to know her properly :-)
