I got this 2 Inch Hole Punch at Hobby Lobby. The logo for Courageous Christian Father is round. 2 Inches is height of a business card.
I have been cutting them out on my own until I got this nice 2 inch hole punch. I got it half off and Hobby Lobby on sale.
It has come in handy. I print out my logo with several on a sheet of card stock paper. Then use the hole punch and punch out the logo.
Now I have a disc I can hand to people when I talk to them about the blog. I can hand them out with a gospel tract, etc.
I am sure you can use it and make your own gospel tracts too. Have a special round one. Of course Hobby Lobby had other sizes, but I believe the 2 inch was the best bet.
This might be an idea for you to use on your Christian Ministry or Church. Maybe you can put Bible verses and cut out the circles and give them to people too.
