I would go ahead with the quilt and have faith that it will be respected as hers. You may want to make a block with a pigma pen stating who it belongs to and when it was made and sign it. Make sure the block is on the front of the quilt and sewn and quilted into the quilt. I believe this would help with the 'security' of the quilt as being hers. Who would want a quilt with all that information on it, that doesn't pertain to them. They wouldn't be able to sell it. Make sure you take a picture of the quilt with your MIL. Also make sure the nursing home know NOT to wash it. Take care of that yourself. Good luck and make sure we see a pic of the finished project. God bless and happy holidays.
