I recently stumbled across Housing Magic while in Marleybone and I bought a few items to try in my house. I followed the instruction steps for the first time successfully. What I am having trouble with is getting to the starting point where I can use housing magic. How do I - for example - use the Grow or Shrink cards, and do I have to use them on items I purchase from the instructor in Marleybone? Can those spells be used on any household item? I tried going back to the instructor (I forget his name) but I cannot get his instructions again. Hopefully someone will explain what I need to do. Thanks in advance for your help.
