Working on a tidier backside
Your back side looks pretty good to me! You're doing a great job! My practice is to use relatively long cuts of floss and use the loop method to cut down on weaving ends back under the work. I also try really hard to not skip over more than two stitch lengths without weaving under adjacent stitches. It looks like you're disciplined about the back of your work, so flip it over and marvel at how great you're doing!
It's a matter of personal preference. That said, I will weave through a few existing threads on the back of my work to get where I'm going, but I try not to skip more than two stitches worth if there aren't any existing threads. There aren't any rules - enjoy yourself and do whatever feels the most satisfying to you. I'm also wary of more than one pass under the existing threads because my taste is to have a front that's as free of ridges and lumps as possible. I do love a neat back side, so I commend your attention to detail!
I currently don’t trust just tucking thread behind a stick or two. Does it really hold?
Oh, goodness, no! I wouldn't trust that either. I was just blathering on about how I get to another place without ending my floss. Like, when there's a space between stitches. If I'm at the end of my floss, I go under a thread, make a loop and go under it again for about 5 sticks, to use your word. Does that make sense? BTW, I like the term "sticks" so Imma gonna use it.
Sorry, no advice, but I would be ecstatic if mine ever resembled that! It's pretty tidy.
Thank you! I’m not a fan of seeing the backside on completed work, so I’m trying to get it tidier.
