Crocheted Childproof Doorknob Cozy

I know that there was a pattern for one of these online once upon a time, but now that I needed it... it was no where to be found. So, being a resourceful gal, I made sh!t up!

This was an I hook and some sugar n' cream worsted cotton I had laying around. Doesn't use much yarn!
Also...I crochet pretty tightly. if you work loose, best decrease the hook!

rnd 1: ch 4, 9dc in 4th ch from hook, join
rnd 2: ch 3, 2 dc in each dc around, join
rnd 3: ch 4, 1 dc in same sp as join (1st v-st made), *ch 1, sk 1 st, v-st* around, join to 3rd chain of beg ch 4
rnd 4: dc in ea ch-1 sp around(including the v-st chains)
rnd 5: dc in each dc around, break off
Chain, I dunno, enough to weave between the dc's in rnd 5 and have some to tie...maybe 6-7 inches. Fit cozy over knob, tie.
Big hands can grip the knob or use the v-st holes to turn it, little hands just make it spin and spin and spin and spin.....
Thoroughly tested on 2 year old nephew AND 63 year old arthritic father. Father can open door just fine, nephew can't. I give me a A+!!
