I made my partner's Valentine card today by hand using some brown card and embroidery thread. I found the pattern at Stitchpoint.
It was so easy and fun to do. I completed mine in about 40 minutes. Using the pattern printout (or your own design), attach the pattern to the cardboard of paper you're going to use for the card with blu-tac or tape, but make sure it can be easily removed without marks.Punch through the pattern and the card with a needle or a pin. I put a cushion underneath my layers to make it easier to punch. When you have all of your punched dots, you can start sewing.
Use a cross stitch, running or back stitch or any stitch you wish to join the dots.
