think of the type of customer she will get. Small gift items, kitchen items like table runners or mats to go under the floral arrangements would be good. Also a small basket with baby items or personal items would go along with the floral items. Smaller bags that could hold a floral item and then later used as a tote bag might be good. If you did quilts, I would recommend the small throws and maybe do them in garden prints to compliment her items. The bigger issue is learning how to price not only to make a profit, but to keep items within the price point her store will handle. Good luck, take it slow and learn every day!
