Lucky, Lucky, you foothills,
As a reforming combi knitter by nature, I can tell you that you have 2 choices.
As Kelly said, and probably the easiest.....instead of knitting from the left in the usual manner, do it from the right side of the loop...approaching the back most part of the loop from right to left. (the opposite of the usual, proper way). See Amy's Combined Knitting video and/or explanation for more info.
Alternately, you can do a combined purl, which you can see in Amy's video on the topic of Combined Purl if you're interested.
I'd recommend the knit stitch though.....as I think the purl stitch twists and tightens things up so much that you'll find it hard to work your proper knit stitch in the follow up row.
Try them both and see which way works best for you. But do not stack one row of Combined Knit with a Combined Purl in the next row....or you'll have created "proper/untwisted" stockinette, thereby defeating what you're looking to do.
Keep it simple and then forget it as fast as you can after you're done with the project. Trust me, you don't want to pick up this bad habit! LOL
