Advice

Ok. I read last night about provisional crochet cast on. I went ahead and did 216 crochet chains (10% fewer of the 240 for the medium size) using Sinfonia, a mercerized cotton, using an F crochet hook. The total length of the chain is definitely longer than the length that I got when I did the same number of stitches in the yarn for the project with US 2.

So my question is: if now I switch to my yarn and US 2 and pick up the same number of stitches using the back loop in the crochet chain, at the beginning it will look kind of wider but I guess it will shrink as I knit the rows with these needles. So, should I kind of knit 1 or 2 extra rows until I get the right gauge and when is time to pick up the bottom stitches of the hem so I can join it with the top, just unravel a few of those extra wides rows.

or
you think as soon as I picked up the stitches will go to the right gauge?
Or I can try to do the crochet chain more tighter but they said to do it loosely.

Hopefully I am making myself clear. Thanks
