Just saw a great easy design on Eleanor Burns QIAD show. You can go to her website and watch it free- it's called Layer Cakes and Jellyrolls- she explained precuts, then showed this pattern in 30's repo fabrics. You can cut your own 10" squares and strips though. She tells you everything you'll need. It's large half square triangles and a piano key border from strip sets. It was finished with jumbo rick rack or you can finish with binding. If your DMIL is developing dementia a door hanging would help her, but only one- don't change it. If it has something on it she really loves, a certain flower or color or her first name this might help her know her room. Put pictures of you and your family in her room and label them with their name and relation to her. This helped my Mom. The best thing you can do is not correct her or show impatience when she forgets or her conversation doesn't make sense. It's hard not to sometimes, especially when you are answering the same question for the -10th time in 20 minutes, but keep smiling and hang in there, you will never regret it. Blessings.
