p3togtbl

P3tog tbl, p3tbl, p3 sts tog tbl, purl 3 together through back loop...however you say it, this can be one nasty stitch to make. Lucky me, the Diamond Rib pattern in Sahara uses this stitch. K3togtbl, which was used in the diamond rib at the bottom hem was at least doable by slipping, knitting, then passing the slipped stitch(es) over. It took me a while to figure out how to easily do the p3togtbl, which is the same stitch from the other side. It was difficult to find information, but I did see a post mention a crochet hook being used.

1) Crochet Hook - The method I used was to stick the crochet hook through the stitches so the hook ends up where the point of my knitting needle would have been had I tried to purl through the back loops. This is the same direction the left hand needle is pointing, which is pointing to the right. After many awkward tries at it, I came up with a fairly quick system. Slip the 3 stitches off the left needle since it'll be nearly impossible to get the hook through the loops while they're on the needle. Take your crochet hook, and stick the butt end left through the loops. You don't have to bring your hook hook-first from left to right, if you stick the non-hook end from right to left, your hook still ends up in the correct orientation. Now, as if you were crocheting, wrap the yarn around the hook and pull through the 3 loops. Now you've got your final stitch coming out of the left and your working yarn coming out of the right. Flip the hook with the stitch around, clockwise as seen from above and put the stitch on the right needle. Similarly, move your working yarn clockwise, bringing it to the back for the following knit stitches.

2) Passing Over - I just realized there is probably a way to do this by passing stitches over. I haven't tried it yet, but my attempt at visualizing this would suggest the following: purl 1 stitch through the back loop. Slip this stitch back onto the left needle without twisting. Slip the next 2 stitches over the purled stitch. Slip back to the right needle. That might do it.
