Here's the link to the exact size basketball slam dunk cake sketch that I printed out:

Printing Photo Inspiration Images from Shawna's Google Docs Files:
To edit the document and change its size...

First, click on the Google Doc link that I've provided. You'll need to have a google account to complete the next steps, so if you want to print from these google docs I add, it's a good idea to setup a google account.
Ok, after you click on the link and the photo has opened in the document, click "file" in the upper left hand corner.
A menu drops down... then click on "make a copy". A box pops up where you can give the file a name and designate which folder in your google drive you'd like to save it to. It should then automatically open up that copied document for you.
You should be able to edit that document (you can only view the original that I posted.) Change size as needed and you can hit the print button when you're finished!

Used for this project:

6" half sphere cake layer (bakes in Wilton Sports Ball tin)
6" round layer (baked in 2" deep tin)
(2) 8" round cake layers (baked in 3" deep tins)
(1) 8" round cake layer (baked in 2" deep tin)
(1) batch ganache
(1) batch Easy Swiss Meringue Buttercream
(2) batches modeling chocolate

Note on Foam Boards:
1/2" thickness with a sturdy outer surface is SUPAH sturdy but a bit pricey. 1/5" and/or 3/16" thick should still work just fine.
It's actually more about the outer surface than the thickness. The outer surface of the Guildcraft kind (the ones I used in the video) are pretty thin and flimsy, but the outer surface of the ones listed in the supplies section from Amazon are much sturdier which is helpful!
