For a recent camping trip I decided I need a portable project and cast-on for the ever popular Star Crossed Slouchy Beret. However, I wanted to mod the cast on for one of my favorite seamless ones. A tubular cast-on for 1×1 ribbing in the round. The great thing about this cast-on is it doesn’t require learning any new maneuvers or stitches, just a little scrap yarn.
Simple Tubular Cast-on Tutorial
First, determine half the number of sts indicated in the pattern plus one. So for this pattern that’d be 37 (72/2 = 36, +1 = 37). Using your scrap yarn, and needles a couple sizes smaller than the pattern indicates, cast-on with the typical long-tail method. Distribute sts for working in the round (on needles a few sizes smaller).
Slip the last cast-on stitch over the first cast-on stitch and off the needle (36 sts remain).
Switch to your working yarn and work: Round 1: *K1, yo; rep from * – 72 sts.
Round 2: P1, *k1, slip 1 purl-wise with yarn in front; rep from *.
Round 3: *P1, sl1 pwise with yarn in back; rep from *.
Repeat Rounds 2 and 3 one more time. You are actually working double knit on these rounds, basically one side at a time. Therefore it takes two rounds to complete one row. At the end of the repeat you have the equivalent of two rows completed.
Now you’ll switch to the indicated size needles and work your regular 1×1 ribbing for however many rows to match the pattern. In this case, that would be three more rounds of *P1, k1* to equal 5 rows of ribbing.
Next, carefully cut the waste yarn in sections and remove.
Ta-da! A beautiful invisible stretchy edge! See the finished hat here.
