First, you'll need watercolors (duh), a small cup of water, a thin paintbrush, a fine Sharpie, and a plain card made out of cardstock.
What you'll need to do is fill up the cup with water, and lay down the cardstock. Then you're done! JK, nope!
You need to write whatever you want to on the cards (for the ombré-ish one I write merci beaucoup, and for the polka-dots, thanks/thank you in different languages).
For the ombré, I used pink and red watercolors. It's not really ombré, but here's how I did it anyway- I made the color very deep at the edges and slowly lessened the saturation so that they "merged" in the middle, but they didn't, so I dabbled the two colors together.
The polka-dots was more fun for me, and easier too! I just painted big circles of colors, and filled in the gaps with words. :D
I hope you will like making these cards- I sure did! They're a very sweet way to show someone you appreciated their gift, and I love receiving cards, since people never send them out anymore. :'(
Have a lovely day! xoxo
