Tacking up pants

[Jacksmom716]

I am crocheting a pair of pants for a friend of mine who can't crochet but she can knit. She asked me to make them a bit bigger so her son will be able to get a lot of use out of them, and she asked me to "tack" the inseam from an 11 to a 10. I'm assuming "tack" must be a knitting term I've never heard of. I told her I didn't know how to but I would figure it out, and she didn't offer any more advice so I am hoping someone here can give me some advice on how to "tack" the legs on a pair of pants!

Thank you!

"Tacking" is a sewing term which means sewing a couple of stitches .
It may not be the best idea to "tack" a knit.  I can see where it could be very difficult to clip the tacked stitches
after the garment was washed a few times.

Tacking it just means to make a hem.  But I do agree that it might be difficult to see the stitches to rip out.  Depending on the color of the yarn and what method you might use to sew up the hem, it might be possible to use a slightly darker or lighter shade of yarn that might not show up much through the right side of the garment.  That way it would still be possible to pull out the hem stitches.  Sometimes a hem on crocheted things end up a bit bulky.
