I couldn't really find a crochet pattern that fit what I was looking for, I tried a few and knitted a few and got a basic idea for the shape/lengths to use and then figured out what stitches I liked and came up with my own pattern for a crochet beard.
I have yet to finish the beanie that I will attach the beard too, though, and I haven't photographed it because I'm super busy with school and things, and I can't find my crochet hook right now to finish the beanie. And quite frankly I'm too lazy to go find another of the same size. Though I know I have one. Somewhere.
Ahem. Back to the point of the matter: the pattern.
I used worsted weight yarn and my missing crochet hook is an H or a K. I forget, and since it's missing.....
Ch42 for the base. Or…Make
it the length you want, plus two. (This length is the bottom of the beard…all
the way across between fastenings on the hat)
Ch2, turn.
DC in third stitch from hook.
3DC (total of 4 on this row so far)
Popcorn stitch in next stitch: Popcorn = 4DC in same stitch,
release loop and insert hook front to back through opening before PC, re-hook
end of popcorn and pull through opening)
[DC, PC] repeat across until end: then 3DC last
*Ch2, turn.
3DC, [PC,DC] across
(this popcorn is done reversed: 4DC in same stitch, release loop and insert
hook back to front through opening before PC, re-hook end of popcorn and pull
through opening—this pops the stitches towards you, keeping them the same as
the previous row) until last 3 stitches: 3DC last.
Ch2, turn.
3DC, [PC, DC] across until last three, 3DC last. *
Repeat from * to * until beard meets the length you’re
looking for: just under the bottom lip. Mine is 6 rows, but it covers most of
the under side of my chin.
Next we’ll make the mouth opening.
Ch2, turn.
3DC, [PC, DC] 8times.
…if you made yours a different length, you can fold it in
half and count 2.5 popcorns in (this will be the mouth opening—mine is about 5
popcorns wide) from that you can count how many remaining popcorns +DC you need to crochet to get to that opening
point. The chain you make has to be equal to the number of stitches you are
skipping, one for each DC and one for each PC.
Ch 9 (or the amount required from the math above)
Skip 9 stitches and DC in the 10th stitch. [PC, DC] across
to last 3 as before, 3DC in last.
Ch 2, turn. Repeat the popcorn, DC pattern across as before.
I only needed one more row of popcorn/DC to make it a good size, so from there I finished by doing slip stitch around the perimeter. I added an extra chain or two around the corners to keep it square, but this is all up to you, get the feel for what works with your stitching and yarn weight.
Once the perimeter was even with a round of slip stitches, I cut the yarn and tied off, weaving in the ends.
My particular beard covers most of my neck here, which is nice in the cold of winter, but aesthetically you may be looking for something else, adjust your number of rows of popcorn/DC as necessary.
