Sorry to dredge up old threads, but I was TRAUMATIZED by the loss of the skull pattern, as I had been specifically improving my crocheting skills merely to make this one craft. So maybe this will be useful to somebody...http://web.archive.org/web/20030605131943/http://www.getcrafty.com/store/skull.html
The pattern is there, and I will copy & paste, just to make sure it's not lost.
"(For personal use only)
Materials: yarn and crochet hook, plus some watered down glue.
Note: I let the size of the stitch dictate the size of the teeth,
which then dictates the size of the skull. So do a test and see how big your
skull will need to be for the teeth to look good.
Start at the top of the head and work your way down
Begin by making a round bowl shape (think of this as a little skull cap)
When you get to location for eyes chain approx 10 and attach
approx 4 stiches over. For the second eye do the same (chain
10 and attach 4 stiches over.) Continue around the bowl attaching
the eye chains as you go.
When you are at the edge of where you want the nose to be
chain 6 attaching chain to where the far side of nose should
go. Continue around bowl.
Once back around to the front make upper teeth, chain 2
or 3 and attach to base of chain. Slip stitch between teeth.
Taper bowl in and where you want jaw bone to go chain approximately
22 stitches. Attach end of chain to where you want other side
of jawbone to go. Slip stitch across jawbone, skipping a stich
where you want to make an angle and do lower teeth same as
Close off bottom of bowl to make it a skulll shaped sphere.
Sew in a single piece of yarn in the nose cavity to seperate
Stuff the skull into the shape you like and using a paint brush
coat it with some watered down white glue (elmers/sobo).
Once dry pull out stuffing "
