circular knitting how to follow this pattern
This request is for a tote bag pattern.
After I cast on 100 stiches and have knitted 46 rows in the round the following instructions in the pattern are:
"Rnd 1 (RS): Pm, pickup 17 sts along side, pm, pickup 100 sts along next side, pm, pickup 17 along next side, pm; join to work in rnd.
Rnd 2: K to next m, p1, k to next m, p1, k to next m, p1, k to next m, p1".
I don't understand what these instructions mean, how do I pick up 17 stitches along side. which side are they referring to and does it mean consecutive stitches to be picked up or spaced?
The pattern also tells you to pickup 100 sts along next side. There are only 100 stitches on my needle so I can't work out what this means! It then tells you to pick up 17 stiches once again along the next side.
This does not make sense to me , I hope you can help me with a clearer explanation.
