My SIL and I are doing the shower for my other SIL. The shower is in 2 weeks.

I have a big comfy armchair that rocks, which I thought would be perfect for the Chair of Honor. However, the chair has been abused by my children for 5 years and the fabric is worn and it has some stains.

Please talk to me about covering it up with some cute fabric, or even a sheet. Is it easy to do? Do I pin it to the back? If I bought fabric at JoAnns, how much would I need? Or should I just get a blue sheet?

TIA!!!
