These spiders are quick and easy to make. There are 2 sizes, the spider measures about 2" and the spiderling measures about 1 1/2". All you need to make them is a small amount of thread, size 3 or size 10, and either a 2.75 mm or 1.75 mm hook. The pattern is available for free here- Crochet Spider and Spiderling.
In the pattern the ends are used to make a loop for hanging but they can be woven in if you prefer. For the spider I used Aunt Lydias size 3 thread and for the spiderling I used Nazli Gelin Garden size 10 thread.
Here are different color ideas from some of the spiders found around Azeroth. Clockwise from the upper left hand side they are the felspider, crystal spider, twilight spider, and ash spiderling.
I hope that you enjoy making the spiders and also try not to get eaten by any!
