Step 1 Yarn over, insert into the stitch, yarn over and pull up a loop. Yarn over and draw through 2 loops. Leave the last 2 loops on the hook.
Step 1 Yarn over, insert into the stitch, yarn over and pull up a loop. Yarn over and draw through 2 loops. Leave the last 2 loops on the hook. Step 2 Repeat that unfinished double crochet 4 more times in the same stitch. Each leaves one more loop on the hook; you now have 6 loops. Step 3 Yarn over and draw through all 6 loops. Do not add a closing chain for this version. Push the bump to the far side before making the next stitch.

Give the bumps a background
From a base of 6 single crochets, chain 1 and turn. Work [bobble in next stitch, single crochet in next stitch] 3 times. Check for 3 bobbles and 3 single crochets.
Turn and work one single crochet into each bobble top and each single crochet: 6 stitches. Use plain rows between bobble rows when you want the bumps separated. The pattern decides which face is shown.
Don’t mix up bobbles and popcorns
If there are 7 loops before closing, check whether you made an extra partial double crochet. If the bump disappears, check its direction before undoing it.
A cluster can use fewer partial stitches and can form a flatter group. Do not replace this bobble with 5 complete double crochets: that is the beginning of a popcorn.
