What would you do if a good friend wanted to come over for some baking fun but you felt your house was too small to be a host?

My daughter has a good friend at school (elementary school), and as often becomes the case, I’ve gotten to be good friends with the mom. My daughter has been there several times to play. They’ve come here but in the summer, when we went to the lake where I live so we were not in my house much. They’ve also come here to pick up or drop off my daughter, but not to hang out in the house.

Last year, I was talking about baking something for the holidays but I didn’t get a chance to, so this year she (the mom) reminded me that I have to “make the cake.”

She called the other night to wish me a happy Thanksgiving and told me her oven is broken. She said she’d like to come over sometime to do some holiday baking together (baking that cake we were talking about last year).

My house is very small. I consider it barely big enough for me and my 9 year old. I have cats (cats that hiss at each other, get underfoot begging for food, generally behaving like cats). The thought of this friend and very nice woman and her two kids coming over to do holiday baking stresses me out. I feel like if my house were bigger, this would be a lovely idea but it’s not.

I’m ok baking by myself in my own house and obviously we can’t do this at her house if her oven is broken, but to me, the two of us and the three kids (my one and her two) in my house is too much.

What would you do or say in this situation?
