he best way to make a place card stand upright is to have a placecard holder of some sort. But there are other ways to ensure your place card stands up. If you are using card stock it would work to secure both the front and the back from the inside of the card in some way. Perhaps a ribbon could be used with double-sided tape. Or you could punch a hole through it on both sides, string it through, and tie a knot it at both ends The easiest way to ensure your pace cards are standing upright is to use a product that is more rigid. If that option isn't available, I would definitely recommend a DIY Place Card Holder like the Place Card Holders from Tree Branches I taught in this tutorial. But if you decide you would rather not DIY them there are options similar to these on amazon here
