Hi, I am just starting to knit a jumper for my niece for Christmas and don’t understand one of the pattern instructions. Any expert knitters out there who could translate this for me please? “Working increases 3 sts in from ends of rows as set by last row”.
Thanks so much for your help

It means the last row you just knitted had an instruction to increase in some way 3 stitches in from the end of the row. Probably something like “K to last 4 stitches, inc into next st, knit to end”.
It is telling you to do the same thing on the following rows (increase in the same way) until you reach either the required length or the required number of stitches.
It looks like you knit 3 stitches then make an extra stitch ie increase
and then before you knit your last 3 stitches on your needle you do another increase ie make an extra stitch.
Sounds like you are increasing both ends of your row.
I would have to look at the row before and the row after to be completely sure.
Is it ends of row
or end of rows
ends of row would mean both ends of the row
end of rows would mean only one end of the row.
Thank you for your response. Here is the section of pattern I’m confused about
Next row (WS): K9 and slip these 9 sts onto a safety pin for button
border, M1, K to end. 60 (64: 67) sts.
Change to 3¼ mm (US 3) needles.
Beg with a K row, work in st st throughout as folls:
Work 2 (2: 4) rows.
Working decreases 3 sts in from ends of rows as set by back, dec 1
st at beg of next and every foll 4th row until 52 (56: 59) sts rem.
Work 5 (9: 11) rows, thus ending with a WS row.
Working increases 3 sts in from ends of rows as set by back, inc 1 st
at each end of next and every foll 6th row until there are 60 (64:
67) sts.
Cont without further shaping until left front matches back to start
of armhole shaping, end with a WS row.
Thank you!
You are brave knitting something for a present. I can just about manage a square which my mum finds a real embarrassment because she is really good at knitting… clearly that talent isn’t genetic !!! I hope your niece loves her new jumper 
I think it just means that on the rows where you increase or decrease you do it 3 stitches from either end of the row rather than at the end of the row as you might normally. It will make the outside edge much neater.
I agree with you.
“Working increases 3 sts in from ends of rows as set by back, inc 1 st
at each end of next and every foll 6th row until there are 60 (64:
67) sts.”
This means that your increases are set in from the edge of the row, so between the 3rd & 4th st from either end. The “as set by back” instruction means that if you look at the instructions for the back of the jumper, it will most likely give more detailed instructions, or in other words, do the same with the increases here as you did when you knit the back of the jumper, and obviously the increases only occur on every 6th row until you reach the number needed for whichever size you’re making.
