You’re very welcome, @walter! 
It sounds like you’ve got a great plan! 
Cleansing everything in the light of the full moon is a great practice and I love how creative your altar is! You are using all your clever and creative skills- I am sure it will come out lovely 
.
Being thrifty is a great way to go, practicing magick doesn’t have to cost much (or any!) money at all! If you’re still on the hunt for budget ideas, I recommend the cheap/free project ideas that were shared in the Thirfty Witch Challenge and the Witchy Thrift Shop Finds thread. Etsy and Pintrest are also great for brainstorming altar ideas.
Best of luck- feel free to share pictures of your altar or witchy crafts when they are ready! I would love to see how everything comes out 
Blessed Be!
