i mistake rib (row1: knit row2: k1p1) in hopes that the scarf would roll....but it does
the yarn is acrylic (not nasty like red heart, this is decent acrylic). can it be blocked to get rid of the roll?
can i lay it out, pin it flat, cover it with a towel and run a hot-ish iron over it?

DO NOT **RUN** the iron over it. STEAM it, when blocked in place. - but no pressure.

Is there really such thing as "Decent Acrylic"?

"The only sin is mediocrity." --Martha Graham

Acrylic is plastic. It contains memory carved in iron because it is not a protein. You can block it all you want and, for a time, it will remained blocked. But, sooner or later, it will return to its original chemical structure. Unlike hair and fur, plastic is not a protein. The chemical make-up of plastic is not cellular. When you give your hair a perm using thioglycolic acid you are breaking down the proteins in the hair and then, during neutralizing, the protein structure of the hair re-forms around the rod to configure to a curl. The same thing happens to blocked protein in the form of wool or fur. By soaking the hair/fur in hot water and then stretching the fibre to a new shape, you are, in essence, 'perming' the fibre into a new shape. When you wash the item it will return to it's old configuration and you'll have to re-block it. There's been talk for years about using 'thio' to permanently 'BLOCK' garments. So far? No cigar. Thio is NOT NICE to hair or Sweaters.

An unfortunate but useful analogy might be: Heat up an old tire from your car . . . stretch it out using two big C-clamps. Let it cool. Release the C-clamps and watch what happens. Ya got ya tire all over again.

Alot of people like acrylic...and it is affordable for many people.

My preference lies with "natural" fibers but am pondering acrylic for a baby blanket just because it will be easier for the new family.

Thank you for the info.

An' ye harm none,
I used an acrylic / wool / viscose blend for some scarves and hats last month when I was just picking knitting back up after a really long break and wasn't sure if I'd like doing it again. So, this stuff was OK and hell yes, I enjoyed knitting as much now as I ever did. The Scot in me prevailed and I had to finish using the amount I bought. One set went to the office holidaze party gift exchange and the other to my neice ( I really gave her cash, but the kids needed to see her open something ). Well, she not only wouldn't take it off, she asked that I go ahead and make the hat to match.

Back to your question, I'm thinking that you are referring to the habit one layer of stockinette stitch has where the edges roll backward instead of laying flat. One of the scarves I made was a seed stitch for about 7" at each end with the bigger share being a k2 p2 ribbing, so that didn't happen for me. The other was a moss rib pattern so it too laid flat. Maybe your mistake rib is too close to stockinette to lay flat. try the moss rib pattern. The one I used was over 29 stitches RS K2. *P1. K3 Rep from * to last 3 sts. P1. K2.
Row 2 P1. *K3. P1 rep from * to end.

So good luck, I think acrylic is okay, especially in blends or for children or people who have to wash the item a lot for whatever reason. Not that I myself have ever dropped spaghetti sauce on something I was wearing, but I've read about that happening.....

That's not the mistake rib pattern I learned. LOL My mermaid scarf I posted a pic of was labeled as being mistake rib, but it did not roll at all. I dunno. Sorry!

I have done that same pattern a couple of times, and tried different things - from just going at it, to slipping the first stitch *always* - and the only thing I have found that even remotely seems to help the curling of this type of scarf is adding a garter stitch border to the edge - 3 stitches or so - and that seems to help - I have blocked my multi colored scarf that I did in that pattern - and even that one, after a while, curled right back up... so I wish you all the luck, but I'm afraid this one might be a lesson we all end up learning... - but listen to MMario - he is warning you that if you IRON acrylic it'll melt... not a good thing for the iron or your scarf :)
