My future MIL is throwing an engagement party for us. We booked the venue and she is taking care of everything else. It is open house style. Originally she mentioned renting linens for the tables. Now she is planning on buying plastic, yellow, tablecloths from Party City. I'm so afraid it's going to look cheap. Is this okay?!? I even offered to rent the linens. I'm trying so hard to just go with it!
