This year, the Valentine's day came in a very busy time, so the card I made was a very quick one. I couldn't share it until my boyfriend received it in the post, so here it is now - he got the one on the left. I also cut out a few more ''training" hearts to practise my cutting, but it was really easy. I am considering making this year's Christmas cards this way.
Any shape works, symmetrical or not, just cut it out of the paper and then fold in various directions and cut out the pattern. The only thing you need to be careful about when cutting is that the holes made in different foldings do not merge and create a one big hole - it doesn't look very pretty.
