Another in my Tutorial Tuesday series, this time a two part Oogoo casting tutorial. Oogoo is fantastic for this, since it won't flow out of the mold and you can loosely sculpt it into the correct shape before pressing the two mold halves together.
You may also place your fabric piece into your mold during step 3, if you so choose. Either way works fine.
PLEASE BE CAREFUL TO LIBERALLY LUBE YOUR OVERLAPS. I CANNOT STRESS THIS ENOUGH, GUYS.
As always, feel free to ask any questions!
