Patt alteration help

Ok so I have a project on hold and would like help. I can’t post links on my phone so if someone can post Distinction by Caitlin Ffrench(it’s on Ravelry) I’d appreciate it. I need help figuring out where to put the PMs & how many to use, I’m using worsted weight and CO 20 instead of the 10 for the patt.

Distinction

Place markers after the first 2 sts, before the last 2 sts, and on either side of the 2 center sts. HTH I also hope it’s correct.

That’s really nice. Now that I have it d/l maybe I’ll see if I have yarn for it. Thanks.

With the co of 20, are you wanting to:

make the shawl bigger?
change the shape of the FO?

The co instructions look pretty standard for a top down triangular shawl, it will get bigger the more rows you work…

Well, I thought that if I was going to use the worsted weight yarn that I would have to double the stitches. I want to keep it the same size because it is big enough on its own with the yarn used in the original pattern. How much bigger would it make it if I use a worsted weight yarn?

I have the right size yarn, I just don’t have the colors or fiber I want to make it with. :frowning: also, what does HTH mean?
