I bought an easel like this one (https://www.ebay.com/itm/3857074887...x11t2rgqgg&var=&widget_ver=artemis&media=COPY) and I don’t know how to set the borders correctly. If you set it to 4x6 on the rulers on it, it is exactly 4x6 with no border. How do you get the top and left border to equal the bottom and right? I seen a video linked on here that said to make a mark on the paper in the top left corner and lip it around to set the border. That works but it doesn’t seem like you should have to make a mark on every pieces of paper should you?
