here is a quick tutorial for the gift card holder that i made yesterday. this works well if you use cardstock or other heavyweight paper. first, cut a piece of cardstock 6-3/8" x 4-1/4".
lay your paper as shown above, with the 6-3/8" side running horizontal. score at 2-1/8" and 4-5/8".
fold at the score lines. using a bone folder helps to make nice crisp edges.
on the end that measures 2-1/8" from the scored line to edge of paper, use a circle punch to punch a semi-circle out of the short end of the paper. if you don't have a circle punch, you can also trace around a spool of thread or other object and then cut with scissors. place red-line tape or glue along each edge of the paper until it meets the scored line. at the other end of the paper, i used a corner rounder to finish off the corners; you can also use scissors to round the corners.
remove the protective backing from tape and fold paper up along the scored line, matching the side edges and making sure that the tape is secure.
fold the top flap down and your card is ready to decorate!
here are a couple of examples of card holders that have been finished...the sky is the limit here when it comes to decorating! these are super quick and super easy to make. have fun!
