just about any issue will be cool to use on a sign. All of mine are 2-sided. That way I get to send 2 messages. I also have my proto-type sign which has a 3' × 2 1/2' piece of foam core taped to a 3/4" dowel. I am only 5'1" and 84 pounds so I need a sign that will be able to spin in my hands as I march and it is heavy duty so I don't get blown over by the winds in San Diego. I have a portfolio of mine, since I have attended so many I save them, and sort of cut and paste with my Xacto-knife and spray-mount. I was trained as an illustrator so I invest time and energy in them.
I made one for my sister which had a gigantic 3-D Taco that was about 2 1/2' and on the other side it said "NO Kings, NO Fascists, NO Clowns, NO Crazies".
This time I saw an image of his bruised hand with the word HOPE! I may put that on one side of mine. Since it is 1 month away something else may take its place.
The odd thing is is that when I go to a protest I want to MARCH and CHANT LOUDLY at the front of the protest. I am passionate and if someone wants to take a picture while I march I do not stop since I'll have to run to catch up to the front again. If they take a photo while I'm standing and listening to the speakers it's OK, but once I get moving I am out of there.
San Diego had 80,000 protesters at the June 14 rally and it was originally reported as "tens of thousands". Only 24 hours later did they give the correct number. I knew there were well over 60,000 just from my view from on a higher elevation. Two marches converged and it was a sight to see!!!
