Magic Forums

I'm pretty new to Magic and I started reading up on alters. I have an incredibly small house so I was planning to have them in my closet (my closet is pretty big). So far I'm interested in Loki and Aphrodite. When I was reading up on Loki I saw that you can't have his alter next to certain alters and would Loki and Aphrodite be ok next to each other? Another concern I have is with the offerings. I have no problem doing them but what happens to the offering? (I must sound stupid rn). If anyone is interested in being my teacher or mentor message me because I could really use the help!
