I crocheted an afghan with very soft smooth yarn (can't remember the name of it). I don't know if I cut the ends too short after knotting (square knots) and then weaving in or what, but my friend says it's unraveling now.
I'm thinking maybe I could use Fray check on each yarn end? Does it dry hard? I wouldn't like that.
The only other option I can think of is to undo all the ends and somehow re-knot and re-weave them.
I need some ideas.
Thanks

I have used fray check successfully, doesn't dry hard and I tie about three knots in yarn before weaving ends.

I always at least double knot before I weave the ends in. I have had to use fray check on mine before I didn't notice that it hardened in anyway. Good Luck!!

I split the threads of each end of yarn and tie them in triple knots around the base stitch before I weave and cut. Haven't tried the Fray Check yet, that is a good idea, also.

I have never tried Fray Check on yarn, but do know that it does not dry hard. If you used a synthetic yarn, I know it does not take kindly to staying the way you want it. I made an afghan one time out of acrylic chenille yarn, thought I had woven the ends in nicely, only to discover later that a DGC (dear grandchild) had untied all the knots. So now I have huge holes that can't be easily redone. I now realize that I didn't leave long enough tails for weaving, next time I will leave them VERY LONG.

I've also had problems with the loose ends not staying hidden. I don't think the knots are coming undone, just the ends coming unwoven. It seems to be more of an issue the silkier the yarn and the larger the hook you use. My friend who crochets very tightly and uses mostly single crochet on her hats does not seem to have as much of a problem.

I'm sorry!! I don't know the best fix for this...I haven't tried fray check. I don't know if you'll have enough yarn to try a Russian join? I've used it a couple of times, though it's been a while. I know there are tutorials online and probably videos now!

When I weave in ends I make sure to run through the inside of the strands of yarn...not just follow the stitches you already made then I reverse directions and do this several times. I weave in long lengths, like around 4". I think the biggest mistake people make sometimes is they only weave in one or two inches and then cut the remaining tail off.

I'll have to try your way of splitting the yarn.
This afghan was crocheted in lacy blocks and then slip stitched together. The blocks themselves are ok since each one was made with a single length of yarn, but the unraveling is happening where the blocks are joined. Since the blocks were so lacy I had a hard time weaving the ends in.

Afghans get a lot of use and I always knot at the end and weave in 6-8 inches of yarn. Fray Check should work for you.
