knitting math

So. The bag I just knit, I knit using parts of three skeins of lamb’s pride bulky (LPB), which are 113 grams per skein. I weighed my leftover yarn - 135 grams. So, 113 x 3 = 339, and 339 - 135 = 204 grams used to make the bag. 204 grams/bag / 113 grams/skein = 1.8 skeins/bag, I think. OK.

Now, Naomi wants me to knit HER a bag. The one I made is quite large. I obviously want to make it smaller. I want to knit it mostly using this one skein of orange LPB. The question is.... The bag which used 1.8 skeins was made by casting on 34 stitches, knitting 34 rows, picking up stitches around the edges to make 100 total stitches, and knitting 64 rounds. If I want to change it to a 1.0 skein Hmm.

34 x 34 = 1156 stitches in the bottom square (can that be? 34 rows x 34 st/row == I guess....)
64 rounds x 100 st/round = 6400 st in body of bag
6 feet of icord at approx 4 rows/inch, 5 st/row, so that’s 20 st/inch x 72 inches = 1440 st
8996 stitches in the big bag.

That would mean 1.8X = 8996, where X is the number of stitches per skein. So, that’s 4998 stitches per skein.

Is this going ANYWHERE? I hate math. OK. So....

20 x 20 = 400
50 rounds x 60 st/round = 3000
icord as above = 1440

that should work. Unless I’m screwing this up. And it’s math, so I probably am. Because that’s probably gonna make a really weirdly shaped bag. Or not? HELP!
