As I posted elsewhere a few days ago, there was an overlocker session last Tuesday at the sewing group I have just started going to. Three of the other ladies had new overlockers they ad recently bought at Lidl's. I said nothing!
Two of them were fine and actually stitched better than mine, The third one though was completely locked up - the handwheel wouldn't move at all. The owner left early to return it to Lidl's.
