I am a visual artist with plenty of experience in teaching adults. I am very detail oriented and a good writer and visual communicator.
For your party I would create a clear pdf that you may print out for each participant or project for everyone to follow along.
If I understood correctly, you would like to paint the signs attached below on your post.
Timeline:
Day one: you send me a photo or description of materials on hand
Day two: I will write up and design instructions to complete the task, and send for your approval
Day three: If need be I will correct any of the information and have it ready to send back in any format that is best for you (It can be a prezi, pdf or powerpoint presentation)
