did a detailed internet research on headcaps and veils and eventually found a pattern but even at my 3rd attempt the result was dodgy and i even managed to break the brand new sewing machine needle...anyway where i could buy a heapcap without a credit card?
I don't know. But if you sew with a lower speed, that might help. If it's thick fabric, use a thicker needle. =)

alas it turns out that my sewing machine was faulty..at least it wasnt me this time
