You have a sharp mind! I made tin signs and tee shirts like this for my church, and friends. I have several other designs too. You should see my pro-baby shirts! Also had signs & banners made to display at the Planned Parenthood protests that I go to weekly.
Do you have stuff made, too? Temu makes good & inexpensive stuff with your designs. (I know — China. But, they get it done, do a good job, at 1/5 the price locally)
