If you are new to my blog,  you will see that I show ideas with the assumption, that you already know how to crochet.  I was taught half dbl. crochet, so that is what I use here.  You can adjust accordingly, if you use a different method.  I figured out these projects by trial & error. I sometimes start out not knowing "what" a project will be.  It just "developes" into something eventually!  I did read about the "scrap scarf" on another blogger's site.  She used the hook to pull yarn through each hole.  I just push it through using my fingers.  Whatever works for you!  Happy Crocheting!
