These directions yield a snowflake that is 6 inches in diameter, with three arms attached to each spoke. To create larger or smaller snowflakes, simply adjust the proportions of the pipe-cleaner pieces accordingly. You can also use more or fewer arms on each spoke.
What You'll Need
Wire cutter or pair of old scissors
Three 6-inch pieces of pipe cleaner, plus six 2 1/2-inch pieces, six 2-inch pieces, and six 1 1/2-inch pieces
Needlenose pliers
Pipe-Cleaner Snowflake Ornament How-To
1. Using a wire cutter or old scissors, cut three 6-inch pieces of pipe cleaner. Then cut six 2 1/2-inch pieces, six 2-inch pieces, and six 1 1/2-inch pieces.
2. Twist 6-inch pieces together at their midpoints to make a six-spoked asterisk. Tighten twist by clamping down with needlenose pliers.
3. Center one 2 1/2-inch piece at the midpoint of a spoke, and twist onto spoke. Tighten twist with needlenose pliers. Repeat on remaining 5 spokes.
4. About 1/2 inch from an arm attached in step 3 (toward spoke's tip), center one 2-inch piece, and twist onto spoke. Tighten twist with needlenose pliers. Repeat on remaining 5 spokes.
5. About 1/2 inch from an arm attached in step 4 (toward spoke's tip), center one 1 1/2-inch piece, and twist onto spoke. Tighten twist with needlenose pliers. Repeat on remaining 5 spokes. Trim arms if needed.
6. To hang, glue a loop of cord to the back of a spoke.
Interior-Star Variation
Cut three 6-inch pieces of pipe cleaner, then cut six 3-inch pieces. Twist 6-inch pieces together. Center one 3-inch piece at the midpoint of a spoke, and twist onto spoke. Tighten twist with needlenose pliers. Repeat on remaining 5 spokes. Twist the adjacent ends of 3-inch arms together, and tighten with pliers.

I have been trying to find the recipe for pipe cleaner and borax,I believe, ornaments. You mix borax and water together and immerse pipe cleaners in the solution. I made these with my daughter when she was young and now want to do the same with my grandchildren. Can anyone help me? Thank you!
I found these too late to make many, but did make a few. Actually I should say hubby made a few. We used a little fluffier pipe cleaner for a larger flake and placed them on our tree. I hope to make more next year.
