Condo knitting is a nifty technique popular in the 1970's. It is very simple - all you need is a small needle and a larger sized needle. While there really is no set rule, a good place to start is the size needle called for on the ball band of your yarn, and then whatever larger size you like. Depending on the size of the needles and yarn you decide to use, you will get very different effects. In the sample below, I used a size 17 needle, and a size 50 needle with Cascade 220. This created a loose, drapey fabric that would be great for a spring scarf or shawl.
Cast on however many stitches you like, using the smaller needle.
Knit 1 row with the smaller needles.
Knit 1 row with the larger needles.
Continue working in this manner; when you are ready to bind off, work a row with the smaller needles, and then bind of as you normally would.
Experiment with different yarns and needle sizes to find what effect you like best. Have fun!
Here is a video on this knitting technique. In the video I use Sugar n Cream cotton with a US Size 10 and 15 needle. I basically just repeat the info here in the post.
