My yarn is on the way for the cowl I want to knit. I use long tail cast on, especially for 351 sts to join in the round but not sure what to do with remaining tail. I know I can Knit some into the first row, but how do I make sure it won’t come loose? I also have this problem once I have cast off. watched the weaving tutorial on you tube, tried it, and everywhere I ended, the yarn began to get frizzy and it looked unkempt What is the best way to keep an end in place?
