Pattern decreasing question

[Alysha]

If I'm reading my sweater patter correctly, I believe I'm supposed to do armhole shaping by decreasing on purl rows. Can this be right?

I'm knitting in stockinette and this is what it says, with the first row being knit:

"Bind off 3 sts at beg of next 2 rows. Dec 1 st at beg and end of every other row twice."

So I bound off 3 knit stitches, then 3 purl stitches on the next row. It seems to me that I would then K 1 row, P the next row with dec's, k 1 row, P with dec's again.

Am I wrong?

Ok, so I'm a fairly new knitter, but I'll take a wild leap here. If I have this correct, I think it's reading like this:
Row 1: B/O 3 sts knitwise, k across row to end
Row 2: B/O 3 sts purlwise, p across row to end
Row 3: k2tog, k across row to last 2 sts, k2tog
Row 4: p across
Row 5: k2tog, k across row to last 2 sts, k2tog
Row 6: p across
Row 7:k2tog, k across row to last 2 sts, k2tog
Row 8: p across
Row 9: k2tog, k across row to last 2 sts, k2tog

Thanks for your reply Newbie! So, you think I start the decreases immediately have my binding of rows?

I only have to decrease a total of 4 stiches; therefore only two rows will involves decreases. So, if you're right, I'd be stopping at Row 5.

Yes, that's normally how most patterns are... BO at the beg of 2 rows, then start the decs on the next row.
