Here are links to different ways to make kaleidoscopes:
Science Works: How to Build a Kaleidoscope
The Ashland Science Works museum has great DYI instructions for a kaleidoscope. This project uses a toilet paper roll and aluminum foil (or shiny cardstock). They put translucent beads into a plastic bag and rubber band it to the roll. This website also explores the science of the kaleidoscope.
Science for Kids: How to Make a Kaleidoscope
This method uses a toilet paper roll and mylar sheets. The author had children draw on a round piece of paper and uses a straw to attach it to the roll. She paints her roll to beautify it. There is a video of her making the kaleidoscope.
DIY Kaleidoscope Craft for Kids
This method uses a paper towel roll and aluminum foil. The author cuts clear plastic circles from a salad greens lid. She glues the clear plastic circle to the open end of the paper towel roll. She inserts translucent beads into the tube and puts the second clear plastic circle into the roll. Then, she inserts aluminum foil covered cardboard. To make it look pretty, she attaches a piece of colorful paper onto the paper towel roll with tape.

This book has directions for a kaleidoscope that only uses mylar glued to cardboard. The author draws a picture on white paper and tapes it to the kaleidoscope. This version is simpler than the others because it does not place the mylar in a tube.
Here are my tips after trying several ways to make a kaleidoscope:
