Thank you! I will look online again. I was afraid that it was a brand that may have gone out of business, like you say, scrubsewer. I would use another type of durable yarn, but it appears in photos that the Phentex is a different type (more nylon-like? almost fabric-y, rather than yarn-like?).
I heard that phentex is made out of plastic and wears forever.. I also heard that it is still available but not that easy to find although an Internet search may find you some. I just found it easier to use the Red Heart Super Saver than to try finding the elusive Phentex, although I have not searched diligently for it. I already had so much Red Heart, and it works well.. especially since I had six grandkids to knit these slippers for and they all wanted their own favorite two colors.. and of course they were not all the same colors either! I have a friend who did find some Phentex and I am considering if I want to make an offer for the couple of skeins that she found. You are right, it has a different texture. Hard to describe it in the written word. The grandkids LOVE their slippers.
I just looked and found quite a bit on Ebay.. worth looking at.. yes?
