Step 1: Tools needed
Step 2: Your design on the Pumpkin
I found a suitable Darth image that was laser etched on to the back or a white PSP (you'll find it if you search google images!)
I saved it, zoomed in on my laptop, held some paper over the screen and traced the outline.
I then cut this out and taped it to the pumpkin.
If your Pumpkin has been refrigerated make sure you allow it to rise to room temperature before you stick anything on it, as condensation will form on the skin.
Step 3: Cutting!
I used the large chisel type blade to chop out the major detail.
start from the middle and work out. This keeps the pumpkin strong. I chopped out the large bits first which was a bad thing to do!
I then changed to the smaller angled scalpel like blade for the more delicate work.
Step 4: Results
I had one problem where I sliced through a major section of my pumpkin, so I used a small carpenters nail to re attach it.
I hope you found this useful, if you have any questions post a comment below and I'll see if I can help you out :)
