Since THIS PATTERN Is insanely easy to manage, I’m going to attempt to write a pattern for a bigger owl. Using the same basic idea, but increasing the stitches all around. This pattern was written as I was crocheting it, as much to keep my attention on counting and to give myself a workable pattern [as well as, write my own pattern *gasp*!]
Gauge is unimportant, as well as hook size. Bigger Hook=Bigger Stitches=Bigger Owl
I used an I hook with worsted weight yarn
Step One; Make a Magic Loop and DC 12 times into it
Step Two; DC Twice into EACH DC around [24 DC]
Three; *1 DC, 2DC in the next stitch* repeat around [36 DC]
Four-Eight; DC for whole round [36DC]
Nine-Twelve; [Change color -optional-] DC for whole round
Thirteen; *1 DC, DC2Tog* around [24 DC]
14-16 DC around [24 DC]
Seventeen; *1 DC, DC2Tog* [12 DC]
Eighteen-Nineteen; DC Around [12 DC]
*Stuff the bird*
Pinch the two layers together and Crochet through them both for; 1 DC, 1HDC, 3 Sl st, 1 HDC, 1 DC [ears]
WINGS [make 2]
One; make a slip knot, chain 4
Row One; DC in second and last chain, ch 2
Row two; DC in each  ch 2
Row Three; DC across [4 dc] ch 2
Row four; 5 DC [continue until wide enough]
Optional; Take another color of yarn and SC around the main color. Make two rounds with it, embellish as you wish.
For the face, just go wild.
The first picture is the actual appearance of the owl currently. The second one, my room mate put Golf Tees for eyes. I liked the placement, so when I add eyes I’ll remove those. They make him look crazy and kind of creepy.
