there are many,many cast on’s… and while long tail (or a version of long tail) is the one i use most often, i know 35 + ways to cast on.
i think, especially for hats or top down sweaters, the cast on, (which in effect frames your face) matters.
for hats, a tubular cast on is very nice…
and so is a 2 color long tail–its super easy, and make good use of the first row of the Long tail (to make it interesting, even if its not in ribbing)
to do a 2 color LT:
take 2 strands of yarn(each a different color) make a slip knot (leave a shortish tail)
make one strand (CC) the thumb yarn, and one strand (MC) the index finger yarn.
now just do a standard long tail
at the end of the cast on, cut the CC (thumb yarn) leaving a 6 to 8 inch tail. continue hat in MC (if desired, add a small motif (fair isle type) with CC, or occational stripe.
back in march, i did a 4 part tutorial on cast on…
(each page has a link at bottom to next page, or just scroll through the march archives.–(if you do, you;ll find part 5, bind offs first!)
There are options beside different cast on’s too.
a latvian twist (cast on a multiple of 6–(long tail) work in ribbing (or stocking knit or even in garter!) for 6 rows. (work straight, not in round)
then row 7, *work 6 stitches–then twist the left needle (turn it 360°!)repeat
after last twist, join into round, continue in ribbing (or garter, or desired pattern…
(i show this done in a stripe (Cast on in CC, 2 rows of CC2, then 2 rows of MC, then twist, then, in my case ribbing in MC)
There are many edging options (and latvian twist is really an edging, it just works to make a Long tail cast on more interesting!) that you can use too.
