Welcome to the knitted bobble tutorial! This bobble technique produces a more "knitted mound" type bobble that is used in my Piece o’ Cherry Pie pattern's cherry filling. It is a little more subtle than some other techniques. The two key stitches are written out in their entirety below. Read through them and then proceed to the step-by-step photos.
bbl inc [bobble increase] k1 (do not drop stitch from left needle), yo, k1, yo, k1 all into same stitch (there will be 5 loops on the needle within the one stitch). Turn p5 back across the 5 created stitches, turn and k5
bbl dec [bobble decrease] slip 2 stitches knitwise, k3tog, pass 2 slipped stitches over knit stitch. Poke bobble forward with finger and make sure to pull the next stitch tight
Knit into the first stitch but do Not drop the stitch from left needle. Yarn over once then insert the right needle into that same original stitch and knit 1 still keeping the stitch on the left needle. Yarn over and knit into it again letting it drop from the left needle.
You will now have 5 stitches created into the original one.
Without knitting any further, turn your work and purl across those 5 newly created stitches.
Turn your work back and knit across the same 5 stitches and continue the row.
You will then purl across the entire row like usual.
When you come to the first of those 5 knit bobble stitches you will work the bobble decrease. Slip the first 2 stitches, one at a time knitwise. (Photo shows the second stitch being slipped). Next, knit the last 3 stitches together. This is done the same way as k2tog, just with 3 stitches.
Now pass each slipped stitch over the k3tog stitch, the same way you do when binding off.
Poke the bobble forward with your finger and make sure to pull the next stitch tight. Remember this stitch is in Reverse Stockinette so the bobble faces the purl side of the fabric.
Congratulations! You've made your first bobble!
