The construction for working the Family Crew Neck raglan begins with the neckband. This makes it different from a lot of other Top Down patterns. Once the neckband is knit, short rows are worked to create a neckline where the front is lower than the back.
Because the neckband is worked first it’s important that your cast on is especially stretchy. Quite often the neck opening of a crewneck is smaller than your head circumference. It’s not a great feeling to rip your ears off as you pull your sweater over your head. Especially if you’re working a sweater for a child.
I’ve looked for some videos for stretchy cast ons. Here are the ones I use regularly.
Many stretchy cast ons are based on the long-tail cast on and I found the third one mentioned in this video to be the best (found at 5:10 into the video). Three Wasy to Make A Stretchy Cast On I used it here and since I use the long-tail cast on all the time, I found the third method really easy to work. I think it looks great with K1,P1 ribbing and it is indeed, very stretchy.
Another great cast on is the Crocodile Cast On by Cat Bordhi which is also based on the long-tail cast on. This is my usual cast on. It is stretchy too.
The beauty of starting with the neckband is there is no picking up afterwards. I count this as a big advantage.
Would you rather pick up the neckband? Are you good with starting with a stretchy cast on and going on from there?
