this was all free form so I don't have I full pattern, but I know I started making a basic skull cap in single crochet and increased until there were 6 single crochets between each increase [unsure as to how many increases were in the round but i place it somewhere between 6-8], then continued to single crochet for about 15 rows. I ended up with 48 stitches/round, divided that by 4 to get the number of stitches I could use for each bottom ghost nubs. I left a long tail that I could weave to an edge to start each limb; the exact pattern I do not know cause some of mine came out uneven (but I like it). that was repeated 3 more times.
for the arm, I used the magic ring to form a circle with 5 stitches. increase all around to arrive at 10. slip stitched around (10), single crocheted around in the back loops only (10), then continued to crochet 10 for 6 or 7 more rounds. I used a triple increase at opposite ends for 2 rounds, and single crocheted for 2 rounds. I divided the number of stitches by 4 and separated the group containing the 3 fingers and separated it from the thumb (thus creating a palm) by single crocheting the larger area for 3 rounds. leaving long tails, I crocheted each finger one at a time, making the middle longer by adding an extra rounds or two. I repeated that for the thumb as well and is about the same size as the smaller fingers.
I slip stitched the details directly onto the body.
I figure the form itself is pretty simple for even beginners to crochet and can be finished by an experienced crochet artist in a day; the body only took me a couple of hours and I've been crocheting for about a year and a half, give or take.
