The best cast on ? for garter? for ribbing? for anything?
its very subjective!
Channel island cast on is one that has been, traditionally, followed by garter.
The real answer is: What do you want out of your cast on?
and what cast on do you know?
and are you willing to learn new cast on's?
there are at least 40 cast on's out there (since i know 40, and i know i don't know them All!)
On my blog i have, in left column, a link to my page of links..
One Page you can find is Page 4 of my cast on tutorial-- it has a bunch of links to OTHER BLOGS, web sights, and books.. so that you can learn about the 40 cast on's i know about.
(i have even started to add YouTube video's of my own for cast ons/ and different methods of casting on.
in some cases, a different cast on is just a different method.. sling shot, thumb and pop gun(aka Maine) are three different methods for creating a long tail cast on.
Once completed, all three methods LOOK identical.
There are a world of cast ons.. and many cast ons will work well with garter stitch.. (i like a small picot cast on with garter.. its very stretch.. but tedious to knit!)
