How to Make Bobbles, Clusters, and Popcorns
Also called the puff stitch, bobbles are made up of several partial half-double crochet (hdc) stitches. After working a bobble stitch with an odd number of loops (for example, 3 or 5). close it by pulling the last loop made through all the loops on your hook.
1 Make several partial hdc in the same stitch or space. Every time you repeat the "yarn over, insert the hook, pull up a loop" sequence, you add two loops to your hook.
2 Yarn over, pull through all the loops on your hook, then bind off partial stitches into one neat package.
Clusters (abbreviated Cl), are partial stitches all made in the same stitch or space. (If you place each partial stitch in a new space or stitch and bind them off together, that is called a decrease, instead of a cluster.) Clusters are most commonly made with 3 or 5 partical double crochet stitches (dc), but you can use treble crochet and other stitches, as well.
1 Begin the cluster stitch by completing the first half of a double (or treble) crochet, but don't work the last yarn over.
2 Make 2 more partial dc in the same stitch by yarning over, drawing up a loop, and then pulling through 2 loops on your hook. Bind off the partial dc by yarning over and pulling the yarn through all the loops on your hook, closing the cluster.
Popcorn stitches "pop up" from the surface and create texture. They are usually made by working 3 or 5 complete double crochet stitches (dc) in one stitch or space, which are then drawn together. Popcorn stitches are often separated by a chain or two.
1 First, make 5 dc in 1 stitch, removing your hook from the last stitch to leave an open loop.
2 Insert the hook into the first stitch of the group, then back into the open loop.
3 Pull the open loop through the top of the first stitch to close the group. With your finger, poke the popcorn to the right side of the fabric's surface.
