I was in a shop last year in a different city,most of her fabrics were dark colors,I like brights & mediums. Being with my sister,I said I didn't care for the colors in the store,was over heard by the owner who was very nice she said that she did order to her own taste & she was trying to order brighter colors,So try to have a wide range of colors in your store,good luck in your dream.I will pray for your success.
