What the hell!! This is the first time I use this size for a project and I'm in the middle of this blanket and the connector has broken off in the needle!!!! This is the BOye set. They kept unwinding while I was working and I was getting annoyed but this is just ridiculous!!
You got them brand new? Contact the manufacturer. Hopefully they'll replace it. Unless they're antiques they still should make it right and with antiques they might not be able to. Whenever I've had a problem with needles, the manufacturer has been very helpful.
I should never overestimate my basic arithmetic skills.
