I used to make handmade cards a long time ago. And I sold quite a lot. These are several that I have left. I used handmade papers that I made myself to make the cards above. I printed the graphics with a cardmaking software and made envelopes to match. I made a lot of bookmarks with these papers, too but I don't have them anymore, so I can't show you.
For this one, I scanned a flower, printed it on white paper and glued it on a square of matching handmade paper.
This card is one of the earliest I made. As you can see, it wasn't so creative. I printed the paisley pattern onto white paper, stuck a sticker in the middle and put some dots with silver pen all around them. Reminder: This was a LONG time ago, so the card designs are very not creative :p
I was crazy with tea-bag paper folding, too. Have you ever heard of them before? If you haven't, check this out and this. And Rosemarie has lots of free tea-bag papers for you to print. What to do with them you ask?
Well....you can attach them to cards for one.
As for the ones below, I didn't have any store-bought stamps so I improvised and searched for black and white copyright-free clip arts, printed them onto the cards, cardstocks or watercolor papers. And I carved my own simple stamps as well.
The ones with a coconut tree, 3 fishes, a dolphin and the one below, I used a cheap technique to add color to the paper by coloring a plastic lid with 'magic pens', sprayed them with water and laying the paper onto it. I got the idea online a long time ago, so I can't credit the creator of this technique.
Seeing all the gorgeous card designs and supplies available nowadays makes me want to start this cardmaking business again. Maybe one day.....
