Hosting a Halloween party is really a lot of fun and something our family does every couple of years. We start the prep and planning early in October, beginning with a party theme.
This year our theme is:
"The Lab" of Dr. E. Vil Genius and The All-Seeing Eye.
One of the first things we do is make the guest list and send invitations. We enjoy the process of designing our own invitations and this year I gave the project to my 16 year old daughter.
She started the invitations by making various sketches of possible designs. We liked this one which is a swirl of the words, "The Laboratory," radiating from a central eye. Initially, she drew it in pencil, then darkened it with black sharpie to create a high contrast illustration.

She scanned the sketch and saved it as a jpeg image. Next, she placed the jpeg into Adobe Illustrator and used the "auto trace and expand function" which converts the sketch into a vector based image and makes it easier to color and make alterations.
She repeated the process with the interior design of the swirl.
After the images are converted, she overlapped them and began to experiment with colors.
She emphasized the words, "The Lab."
Next, she experimented with colors.

She also enlarged the all-seeing eye.

The final design looks like this.
Next, I wrote the inside copy for the invitation. I had just received a "summons" myself for jury duty, so it influenced the copy I wrote!

We printed the invitations on grocery sacks cut to fit our laser printer. The color and texture of the recycled paper added an aged dimension similar to what you might find in an old, haunted laboratory.
We hand-cut squares of black paper and folded them into envelopes.
The final touch was a 1"x 1" eyeball sticker placed to seal the envelope shut.
We also printed out several large versions of the eye to hang throughout our house on the evening of the party.
