Guest Contributor: Sandra Strait on Semi-Transparency

More skills for your drawing repertoire! Guest Contributor Sandra Strait goes above and beyond with this highly detailed drawing techniques tutorial on how to make an object appear semi-transparent. She illustrates two versions, one using color and one in black and white.

Semi-Transparency

Guest Contributor, Sandra Strait

Afraid to use color in your Zentangle-inspired art? I often see comments to that effect. Well, this is one example where color is easier. When implying semi-transparency, contrast is key, and color can help.

That said, it’s fun to know how to do semi-transparency without color, as well, so I’m showing it both ways.

I normally use pen for this, but I wanted a simpler method, and since many of you use those little golf pencils, I’m going to show you how to use them (but any soft lead pencil will do) for bubbles.

You will also need an eraser. I know. No mistakes in Zentangle®. In this case, you will be drawing with the eraser. None of those pink erasers or pencil tips, though.

I’m showing you the technique in both color and B&W, and doing it side by side so you can see that the method is pretty much the same.

I’ve chosen a bubble with a Knightsbridge background for my tutorial. Knightsbridge is a powerful tangle, but so easy to do, and hey! Bubbles are always fun! To keep things easy, I’m advising where to put the highlights, but you are free to put them wherever you like.

The Tools

1. Black Ink pen – I used a .01 micron. You might also want a thicker nib pen for filling in the Knightsbridge squares.
2. Soft lead pencil. One of those golf pencils works fine.
3. White pen or ink. I used a Sharpie Poster-Paint Marker. Gelly Rolls are good. Elmer’s White Acrylic would be good. Use whatever will dry opaque.
4. Paper stump (tortillon) or something to smooth your pencil shading. A finger will do as a last resort, lol!
5. Eraser. I used a kneadable eraser. A gum or soft plastic eraser will do. NO pencil tips.

Optional:

• A sheet of scrap paper to place under your hand to prevent smudges. Pencil is messy.
• Pink, Blue, Yellow — if you are going to use color. I used Letraset ProMarkers, but pens, color pencils, sharpies—you choose the media. Pastel colors will be the easiest to work with.

Step 1: Draw the Bubble

Draw a circle. Don’t stress about the shape. The best bubbles are those big wobbly things, right? Don’t worry if your lines don’t meet. I’ll tell you how to fix that later.

Step 2: Start the Shading

A bubble is darkest in the center, so we start there. Leave a white ring around the bubble.

Step 3: Add the Highlights

We’ll be working around the highlights, so let’s add them now. Notice that this is very similar to what we did when drawing a translucent object.

Step 4: Darken the Center

We continue to add shape. The outside of your color or pencil shading should follow the outline of the bubble. Work around the highlights so they stand out.

Step 5: Add the Background

Add the Knightsbridge tangle in the background. Bring the lines right up to the bubble outline, but don’t go inside.

Step 6: Add the Inside Grid

There are a few tricks to emphasize the bubble’s shape. What you don’t do is as important as what you do do (hmmmm. That doesn’t sound right does it?)

Here are the don’ts.

• Don’t let the lines of the inside grid meet the outline of the bubble.
• Don’t draw through the highlights.
• Don’t align the lines inside the bubble with lines outside the bubble.

The Do’s

• Do curve the lines slightly, because the bubble is round.
• Do have fun. Close is good enough!

Step 7: Fill in the Inside Grid

Here’s where you see that color is easier. Use your pencil and shade each square. Keep most of the white ring around the circle.

Step 8: Erase and/or Re-pencil

You may need to play around a bit, but don’t get stuck. Stay as light as the bubble, lest you burst it!

Step 9: Finishing touches

A bubble’s outline is seldom solid, so put a touch of white ink along the outline. Do this on a white square so the line disappears. I know sometimes gel pens get muddy, but that’s okay. Even if you just lighten it, it helps.

If the lines of your circle didn’t meet when you drew it, use the white pen to obscure that. It if really didn’t meet, then shade with pencil and smooth it.

The last step is to shade around the bottom and left side of the circle to help ‘lift’ from the background.

Drawing something semi-transparent is pretty complicated for tangling. But it’s fun, and tends to impress the heck out of people. It gets easier with practice, so if you want a show stopper in your repertoire, semi-transparency is a good one.
