I am not going to give you step-by-step instructions as you can find them online. The best instructions I followed were from Maggie's Crochet shop on Youtube. I did find that there are various ways of doing this and various numbers of loops to pull through. The first one I made I used 10 loops on the crochet hook which seems to give a bit fuller of a scarf and that used almost a whole skein of yarn. Another tutorial said to use less and so I tried 6 - 7 loops instead and then I could get two scarfs out of one skein. I prefer it that way. The only problem I occasionally had in the beginning was pulling the loops over the initial loop on your hook. If you aren't careful it may all slide off the needle and the scarf begins to unravel. I now did find out that you can buy stitch markers to resolve that problem.
I love all of the colors and I think I have made about 10 of them so far. But I found two more skeins of yarn that are pretty and it is so much fun so I guess I'll whip out 4 more.
I "crocheted" my scarves while the guys watched football and such. I had a helper in that Pete would sit on my left unraveling the yarn for me so it made the process that much faster. Now I am able to make one in about 1/2 hour. I often told the kids how my Grandma would sit on the couch while we watched a movie at their house with her knitting needles clicking away and now I can do the same thing.
