This pumpkin is worked flat, seamed, then cinched in order to create the 3D pumpkin. This pattern includes several photos to assist with the star stitches, as well as clear instructions (with photos) for assembly. You can modify the size of your pumpkin by adjusting the weight of the yarn, but if you would like to make a very large pumpkin, instructions are included for adjusting the pattern. You can use any weight yarn, just adjust your hook size accordingly.
