Just wanted to show you the way my note card looks on Libre Office. You'll be able to adjust the size of the card.
I opened it in writers document. And printed it out using a light weight white card stock. That way it won't seem "flimsy" as it would if you used regular printer paper. Shown below is the finished product. My digital camera did not get the focus right so it looks fuzzy. But you get the idea.
Give it a try on your computer... I think you'll be pleased with the outcome. :)
