Decrease 37 stitches. How to?

[COLOR=Red]These are my instructions:[/COLOR]

With smaller straight needles, cast on 150(158-166) sts.
[B]Row 1 (RS): [/B]K2, * p2, k2; rep from * across.
[B]Row 2: [/B]P2, * k2, p2; rep from * across.
Rep these 2 rows until piece measures 4” from beg, end on RS. Change to larger needles and p the next row, dec 37 sts across – 113(121-129) sts.

[COLOR=Red]How and when do I decrease 37 stitches? I can’t imagine I drop them from the beginning or the end. Here is the pattern:[/COLOR]

I’ve yet again bitten off more than I can chew but I just can’t give up yet.

Thanks.

Hiya hun,
you would decrease them evenly along that particular row. You can figure out the basic frequency for your decreases by dividing the total stitches by the amount to be decreased. You should come up with a number for stitches between decreases.
so let’s take your example and use that
we’ll use size small…
take 150/37= 4.05 so you would decrease every 4th stitch or so.
Hope that helps.

As you purl the next row, do p2tog every 2 sts… p2, p2tog, p2, p2tog etc.
