A few weeks ago I had re-swatched all of my bottles of Robert Oster Signature fountain pen inks. An idea came to me that I should do something similar with all of my tubes of Daniel Smith watercolor paints.
I looked around on the Internet and could not find a decent swatch card system to use. I tried using my Col-o-ring cards, but the paper was a bit too thin to handle the amount of water and paint I use. Being the creative person that I am, I did come up with a brilliant solution.
I remembered I had a few Canson journals left over from my pen & ink workshops and I knew the paper in that journal could handle a decent amount of water and paint. I grabbed my paper trimmer and my corner cutter and I was ready to do some paper cutting.

Since I was familiar with the 2″x4″ Col-o-ring size card, I thought that would be a good size to start with. After doing my initial watercolor swatch tests, I decided the card was a bit too wide. I did another swatch card test and found a 1.5″x4″ size card was perfect for my watercolor swatching needs and I had enough room to write down important color information. This smaller size also allowed me to cut a few more pieces from a single sheet of paper.

I used my Arteza water brush to paint out the colors on my swatch cards. I used my Platinum Preppy filled with Carbon ink to write out the paint color information.

Here’s a picture of my corner cutter. There are three slots (small, medium, & large) for three different size corners. The illustration on top of the gray hand press shows what the corners would look like for each size.

For my swatch cards, I decided to use the (S)mall corner cutter setting to give my cards a smaller or narrow curved corner.


The mixed media paper handled my watercolor mixture well. The paper does buckle slightly when wet. After the paper dries, it straightens out on its own.

Since I was in a paper cutting mood, I went ahead and created my own Col-o-ring-like swatch cards for my fountain pen inks. Good thing I keep several pads of mixed media and drawing paper in my art paper stash.
In the following picture, I used the “L” or large corner cutter. I placed the corner of my paper into the slot and pressed down on the gray handle to cut out a curved corner.

Can you tell from the picture below, which card was the one I created?

I created the card on the right. The one on the left is from Col-o-ring.
