Lenormand
*slinks in*
Someone tell me why I shouldn't buy a Mme Lenormand deck. I took a few months off of tarot because life happened, and now I come back and I want all the decks. :/
It's a whole new system to have to learn, combining cards, you will have to use at least a simple spread, you won't get enough information from just one card.
Also I have only two decent books on the Lenormand which are written in English, but there seems to be many more written in French. The decks are small and cheap so you won't want to just buy one, you'll want them all, you might even spend months tracking down one with English verses on and then find Amazon is selling a brand new reprint of it, especially when you've given up all hope of getting one with English verses on.
Also you might spend hours printing out any useful information you can about these little addictive cards because resources about them, written in English, are slim. You might even spend hours in the Lenormand section here, reading through and printing out, takes loads of paper and ink.
