These lovely, botanical postcards seriously take less than five minutes to make. Here's how to create your own:

∧∧ Take a stroll around the garden and choose some leaves in shapes you like Pro-tip: For best results, choose leaves that are soft (like geranium), not hard (like eucalyptus), and beware leaves or stems that are too fleshy as you'll just create mush rather than patterns

∧∧ Position a leaf on a piece of paper, then cover it with a paper towel Pro-tip: Try to have something flat-surfaced but cushioning underneath it, such as cardboard or several sheets of paper. You could also use a cutting board, that gets VERY loud

∧∧ Holding the paper towel in place, start hammering all over the leaf Pro-tip: Keep hammering until you can see the complete outline of the leaf in the paper towel, then hammer a bit more in the middle to fill it all in. Don't forget the stem

∧∧  Take off the paper towel and peel away the leaf to reveal your lovely stamp!

I made the postcards you see here using watercolour paper because it was thicker and could survive the post as a postcard. Once I'd created my botanical stamp, I just grabbed an old postcard and tore around it to get the size right. I also made some other stamps on standard copying paper, which I'll cut out and paste onto cardboard to create greeting cards.

This was a very child-friendly activity, with my three-year-old and my not-even-two-year-old both helping me, although much to their frustration I insisted on "helping" when it came to the hammering bit.

What do you think? Will you try making these?
