I got a wool sweater at a yard sale and took it apart to make soakers out of. I found live stitches when I did this, so I started frogging the sleeves. I sewed the two sleeves together at the seam (to form a crotch), and frogged down to that point. I picked up the stitches on size 4s (about 120 stitches). This is a 7 ply yarn (some places it's 5 ply?). Can I knit off the 4s onto an 8 (I only have an 8 and an 11 in circular)? I know that's going to change the gauge considerably... is there a way to deal with that? Or do I need to go buy a 4 or 5 circular?
