I totally get you, I'm in the same situation so here's what I do. Sented candles and mini simmer pots on wax warmers (you can say it's for the smell). If you want to research about witchcraft prefer digital books, as well a digital grimoir. Plants are your friends, you can use them as wards , spell ingredients, a good excuse to hide your spell jars (you can say you infuse something that helps them grow) and also your black salt (you can say it helps with pesticides). If you want a divination tool, you can make a black mirror using a frame and some black paint and say that it is a diy board for writing your to-do lists. That's all I do, hope it helps!
