the tan squares were indeed from a Thimbleberries Block of the month club. There were 12 and each one was symbolic of the month. The doves with the heart were February, the rabbit was April. the name of the pattern and BOM club was 'Vintage Stitches' My Mother in law was making this quilt (along with about 24 others) before she passed on. I have each monthly kit of fabric tied up with a little string - but unfortunately not the directions!
