Five Star Gift Ideas

For your grandpa, who really likes soap making, you could consider:

1. Soap making kit: You could get him a soap making kit that includes all the ingredients and molds for him to make his own soap. This will allow him to explore and create new fragrance combinations.

2. Essential oils: Purchase a variety of essential oils that he can use to scent his soap. You could get him oils like lavender, eucalyptus, peppermint, and lemon, among others.

3. Soap making class: If there's a local class or workshop on soap making, you could gift your grandpa with an experience to learn the techniques and processes of making soap.

4. Natural soap gift set: You could purchase a gift set of natural handmade soaps that are already made. This will give him ideas and inspiration for his own soap making.

5. Customized soap mold: Get him a customized wooden or silicone soap mold that he can use to make his soap in unique shapes and sizes. He will appreciate the thought and effort that went into this personalized gift.

Or you can get him a star map with the date when he was born.
