Your flowers are lovely. It is nice to have that much light both for sewing and your flowers. I have at least 8 violets that I have kept alive in selfwatering pots for at least 20 years. They reside in a drysink in my kitchen. My Dad was a florist and told me the secret to having violets bloom and thrive is to keep them pot bound. My husband likes to tease me by threatening to repot them for me. When they look straggly I just pull them out of their dirt chop off the longest roots and replace them in their pots. They bloom like crazy.
