So I have done several socks already, and I'm not 100% happy with my heel results. They fit great, but I do have some small holes.
I use a short row technique of simply knitting one less stitch per row until the correct number of stitches are on the needle. Then I start adding them back in by knitting the last one on the needle together with the first non-knitted stitch, closing the gap. And then since I just did a k2tog, I add that stitch back in by picking up a stitch between the 2 needles. I think I have been doing this wrong. I have been picking up a bar with the left needle and then knitting it. I think this is pulling open a hole. My guess is I should be doing a normal pick up like I do (with my crochet hook) to make a stitch where there wasn't one.
But, my bigger holes are when I am done with the heel and begin to knit in the round again. Someone suggested that I pick up stitches here to and then just decrease it a few rows in. Will this work? How many would I pick up? Which pickup method should I use?
