Painting Seashells (with watercolor)

If you’ve followed this blog for a long time then you know I LOVE seashells. You’ll also know that I love watercolors so I thought it would be fun to combine these two loves – painting seashells with watercolor.

I know for many people the kids have already gone back to school, but here in Scituate our kids will be out on break until next Wednesday; so I’m still in summer mode here.

I thought this would be a great painting project to share – highlighting some beach treasures. You can use any shells you have on hand for this project. You could also use beach rocks, sea glass, pottery shards, or driftwood.

What I love about this project is the organic nature of shells. The layers of color and detail make me so happy and I find them very relaxing to paint. There’s nothing quite like getting lost it the brush strokes while painting in the sunroom.

Here’s what we’re gonna do. Grab some supplies and beach objects and read on for the materials and step by step video.

Why You’ll Love Painting Seashells

  • It’s relaxing
  • You can work at your level.
  • The curved shapes are fun to paint and I find it easier than painting straight lines.

What You Need for Painting Shells in Watercolor

I also enjoy lighting a candle. I’m a huge fan of Minot Candle Company. I usually have a cup of tea or coffee by my side and always play music in the background.

I created a video tutorial and I’m including a step by step card at the bottom of this post. You may want to watch the video through first before attempting your own shells.

Step by Step – Tutorial for Painting Shells

  1. Start by drawing or tracing your shells. Make sure to either make the pencil lines really light or lighten up line work with kneaded eraser.
  2. Create light washes over your shell shapes.
  3. Slowly increase the intensity of the colors over time. Working in layers will give you more control and also help the shell to appear more 3D
  4. Use smaller brushes to create fine details.
  5. To make a shell look three dimensional concentrate on making the sides darker and adding a shadow to the shell. To create the shadow I use a mixture of a light gray and the color that is found in the shell so the pink shell I added a light alizarin crimson and the mussel shell I added a little indigo. Soften the shadow line with a clean brush.

FAQ – Answering Your Questions

What watercolor paper should I use?

I actually just wrote a post all about watercolor papers and why I prefer some over others. You can see watercolor papers I enjoy!

What can I use as reference if I don’t have the shell or item I want to paint?

If you don’t have any shells or beach treasures. You can look online for some inspiration images. I would just recommend not copying a photo completely as their is intellectual copyright.

I’m not the best at drawing. Can I still try this tutorial?

Yes. You can outline the shells lightly with your pencil to get the rough shape and then go back and add details. Be sure to remove any pencil markings with a kneaded eraser because the watercolor can sometimes make it permanent to the paper.

What brushes are best?

I really love these velvet touch brushes. They are pretty affordable and maintain the shape. I actually wrote a whole post on watercolor brushes last month.

Notes

Watercolor paints dry 10% lighter so factor that in whilst painting.
If you place watercolor on top of watercolor while still wet the paint will bloom. This can have a wonderful result but you need to be aware of wet on wet or WOW. You will see a little of this in the video but it’s mostly applying layers onto dried paint.
If you already have paints you are happy with you don’t need to buy the ones I used. You can do this same tutorial with the colors you already have.
