I'm telling you exactly increase place.
NO increase in every front row.
1st row (front): take 3 stitch like knitting and do them 5 stitch, again take 3 stitch like knitting and do them 5 stitch
yes you said "What are you getting at?" :)
3 stitch -> knit, increase, knit, increase, knit. and now it is 5 stitch, Repeat the same operation once again.
2nd row (back): all purl
3. Row (front): all straight knit
4. Row (back): all purl
5. Row (front): repeat 1st row
So every inrease row, you're going to have two five-part sections next to each other.
I hope I can explain good luck ...
