This is another fun and easy DIY that I really like. And you don't need a lot to do it!
+ A fake pumpkin (I got mine from Michael's)
+ Paint brushes
+ Chalk paint
+ White acrylic paint
Make sure you use a nice thick medium brush and put two - three coats of the chalk paint on the pumpkin.
Wait for it to dry completely before applying another coat, because chalk paint can be runny!
Let it sit and dry now! I usually let things like this dry overnight.
The use a smaller-sized brush with your white acrylic paint to write the script. And let dry, of course.
