Bramble Berry recently sent me a set of their rainbow micas for cold process soap. I immediately set to work creating a series of rainbow soap designs. This rainbow tiger stripe design is easy to make and the finished soap is bright and happy looking.

For more tiger stripe soap designs, check out Holly Berry Tiger Stripe, Mermaid Orchid Tiger Stripe and Juniper Lemon Yogurt Soap. The tiger stripe is one of my favorite designs to do in cold process soap!

The rainbow mica set from Bramble Berry comes with 7 colors. I mixed the Party Pink + Merlot to get a reddish color and I mixed the Kelly Green + Caribbean Blue to get Indigo.
