Help! Translation needed!

This sweater, the Sunshine Wrap from August's Knit 'N Style Magazine, is my first project for myself in a long time. I am a little nervous because it needs to fit and I don't know anything about fitting patterns. But I loved the crossover tie and decided it might provide enough adjustment to counteract my shortcomings on that front.

I'm not making it in yellow, but in a lovely russet yarn our buddy Barbara Bretton gave me. I cast on and have navigated the first set of instructions without too much angst. However, I was reading ahead (as my teachers trained me to do in school) and came across this sentence and I am confused.

"Cont in St st, inc 1 st at each end of next and every foll 4th row twice, every RSR 4 times."

Could someone please tell me how many rows I'm supposed to increase on? I keep rereading this and I can't figure it out.

(Also any advice on the best increase method would be much appreciated. I feel like I read somewhere that it's better to increase on the second stitch of a row--but maybe that was in reference to decreasing instead.)

I'm depending on the experts here to unbefuddle me.

Advice Well-Taken

When you guys speak, I listen. To prove it, I offer up photos of the swatch I knitted at your suggestion to test the giant black MIL sweater's felting potential (complete with 4 inch square in red thread for gauge testing). You probably can't really see the difference in texture from the photos but it worked brilliantly. The Cascade Eco+ firmed up nicely so I don't think she'll have the stretching problems any more. However, thanks to swatch testing I didn't overfelt it--the texture is still very sweater-like. The sleeves shortened just enough while I was able to block out the zipper section so it didn't ripple.

Another case in point: following your helpful advice, I took the Rather Huge Noni Bag to a shoe repair shop to have the leather handles sewn on (since my New Jersey suburb isn't rolling in saddle shops--LOL!). He did a wonderful job of making the handles strong and secure.

Here's the up close photo of the shoemaker's stitching.

And here's my Noni Bag all ready to carry yarn, books and the kitchen sink. Did I mention it's Rather Huge?

Thank you all for the incredibly useful, truly fabulous suggestions! What would I do without the yarn geniuses here on RTY?

Oh, and Happy Valentine's Day!
