I got crafty a couple of weeks ago making name cards for a wedding lunch at Petersham Nurseries. I've always had a thing about watercolour stationary so gave it a go myself; it couldn't have been more simple to and they turned out to be rather pleasingly professional looking.
If you would t to re-create them, you will need;
A wide-ish paintbrush
Alphabet rubber stamps
Start by painting the sheets of watercolour paper with the paint.
Wait for them to dry and then cut up the paper into the shape of the name card you want. If you want straight lines it does pay to use a ruler.
Whip out the rubber stamps and ink and start stamping.
Easy as pie...
