I have knitted a blanket with weight 5-6 acrylic yarn and size 8 needles. The knitting is very tight so the edges roll up about 3-4 inches all around. I am curious if there is any type of edging that will help this lay flat or do I just need to block the entire blanket before finishing the edges.
It must be knit in stockinette? Stockinette always curls. It’s just the nature of the beast especially if you knit tight.
I’m sorry to say that even a border won’t always make it behave well. It’s worth a try though. You may need to make it several inches as a little one or two inch border probably will curl or fold in on itself. And make sure it’s a non curling border like garter or seed stitch.
