I was at JoAnn fabrics last week. We don't have one here, but DH had a Dr's appt in Burlington VT. I saw a blade, 60mm, for a chenille cutter. It is a round thing that you can use. The blade was on sale for $2.99. Of course, there goes my brain. If this a 60mm, it must fit my Dritz rotary cutter. I am able to use Fiskars and almost any other brand that size. Well, I got it. Forgot all about it and finally go into my sewing room today. Found it, tried it, and it works great. So, I got myself a new blade for $2.99 and it stronger than regular ones, so it may last me longer. We go back on the 20th. I am hoping they have some left. I guess if they are on sale is because they didn't sell to begin with. Doing a happy dance here.
