The blade fits in my Fiskars rotary cutter, too, which is awesome! (I purchased it at JoAnn Fabrics.) I tried the blade on a piece of scrap fabric and it cut very well. Once I took a closer look at the towel, I decided I really didn't need the blade. The towel is, shall we say, a looser weave...I got it at the dollar store. So I could use just a regular size 7 hook and had no problem poking through the fabric. Once I got into a good rhythm, it was easy to space the stitches pretty evenly.
I used this edging pattern.
I think it turned out cute! I'm excited to do a few more tea towels or crochet an edging on some pretty pillow cases...I will probably use my new blade on denser fabric.
Thanks for checking in!
