Cast On a Needle by Kollabora Follow Once you made a slip knot, you need to cast the yarn on the needle. This video shows how! Many thanks to our friends Waejong Kim and Anna Pulvermakher from Loopy Mango in SoHo, New York!

It would be helpful to always declare which is the working needle. sally commented 8 years ago This is SO HELPFUL!!! I've been doing it the hard way for years, making individual slip knots by hand ;). p.s. Beautiful fire engine red yarn.
