Nice touch on this sharing.
I'm not doing any pumpkin carving but I saw from another post suggesting getting motif template from the internet to print and use that as a guide. So, being busybody, I tried different searches and this works best for me

Google on: free pumpkin carving motif template

See if my search result link works if you are interested:
