Increasing, at its most basic, is simply adding another stitch to the total number on your needle. The potential problem is that there are many different techniques for knitting increases, which can make it seem very confusing!
In Berroco patterns, we tend to leave the choice of increase up to the knitter in most cases (in situations where the increase needs to be a specific type, the pattern will specify). When you’re left to your own devices to decide what increase to use, it can feel a little overwhelming. My recommendation is to use what we refer to in our patterns as a “Make One,” which can be worked as either a knit stitch or a purl stitch. For a demonstration, check out my how-to video:
This little increase is easy to memorize, and once you’ve gotten the hang of it, you’ll find lots of uses for it. It blends in well with the rest of the knitted fabric, and it won’t leave a hole. And since it can be worked either as a knit stitch or a purl stitch, it can be worked on either the right or wrong side of your knitting. It’s a perfect all-purpose stitch that you’ll use over and over again!
