I agree with
Sheltie'sMama's suggestions.
Actually I would go one step further and applique her name right on the front of the quilt.
Perhaps one of the corner blocks?
Perhaps there are some other significant things that could go in the other corners as well?
Date of birth? Marriage Date? Husband's name? Kids names? Grands?
With only mild/moderate dementia, these might be good reminders for her,
or give visitors things to discuss with her.
The flowers definitely make the quilt look more interesting.
Plus they make it look like you put more time, care, effort and love into making it.
Yes, as you can tell I am voting for the floral version!
Good thought .... you may want to make sure that they are well stitched in place, as sadly dementia patients often are "pickers" and could soon have the flowers picked right off!
