ok im having trouble with increasing 1st at each end of rows when its on a purl side?? i can only find videos demonstrating it on knit sides ?
someone please help me out

This video shows a couple of ways to increase on the purl side. Sometimes you need to do the increases on a purl side because of the shaping of the item you’re making. There are also times when one row more or less won’t matter and you can move the increase to a knit side without obviously changing the shaping.

Well, it’s sort of like making an increase on the knit side except done like a purl stitch. The Glossary has one for pfb, for a m1 just pick up the strand between stitches and purl into it, making sure you have a twist in the strand you pick up.
