Tubular Cast-On for 1x1 Ribbing
Step 1: Leaving a long tail, make a slip knot and place it on your needle. Hold the tail and working yarn as for a long-tail cast-on.
Note: If you are casting on an odd number of stitches, work step 3 before step 2 then continue to step 4.
Step 2a: Now bring the tip of your needle over, then under the tail...
b: ...then swing your needle over the working yarn...
c: ...then back under both from back to front. This creates a 'knit' stitch.
Step 3a: Next bring needle tip over then under the working yarn...
b: then swing your needle over the tail...
c: then back under both from front to back. This creates a 'purl' stitch.
Step 4: Alternate steps 2 and 3 until you have cast on the desired number of stitches, ending with a 'knit' stitch.
Step 5: Now you can begin working your foundation rows; knit all the 'knit' stitches (through the back loop for the first row), and slip all the 'purl' stitches purlwise with yarn in front. Once you have worked two rows in this manner you are ready to begin your 1x1 ribbing.
