You can back me for as little as a dollar, and
cap your backing at a dollar a month, and
get all my Patreon content at that backing level plus the card!
There are, unfortunately, some months where I don't post a funded piece of art -- and so you don't have to pay that month -- but I usually post some free content to keep you occupied. (Old sketches and stuff.)
There's no reason to break anyone's budget.
