Ive finally decided to take the plunge and buy a garter carriage for my Brother machine, not only so I can do some nice fancy garter patterns, but also so I can cast off quicker!!!! The other day I had to cast off the whole needle bed width and it took forever! With this monster it will get it done much quicker than me. Im really chuffed with it. It casts on, knits ribs and garter patterns.
