This pattern is for a Christmas hat for Søren, the giant moose.
It is NOT the pattern for the moose. This is available here: http://www.ravelry.com/patterns/library/sren-the-giant-mo...

You can also have a look at Søren’s other outfits. The normal pants and the Christmas hat are for free :)

For the pumpkin you need to know:

chain stitch (ch)
single crocht (sc)
double corchet (dc)
front post dc (fpdc)
increase
decrease

If you have questions, just let me know. Have fun :)
