I was reading with interest your overlocker comments as I have just bought my first overlocker (the Bernina 700D). I have always wanted one so this is really exciting for me. I have had my first go today and 4 thread overlocking is great (stretch nightie for my daughter) but couldn't get a good rolled hem. Bit loopy on one side and not much on the other. Both sides should look the same? I followed the suggestions in the manual but I'm very new to this so any help would be really appreciated.
