If you are looking for decorative items (mass produced ones) for either outdoor or indoor, you can consider visiting a DoHome store. Usually customers would visit DoHome mainly to purchase materials for gardening, building, furniture, construction and electrical appliances.
However, I do notice that DoHome also have a huge selection of decorative items both for outdoors and indoors. At least for the DoHome outlet (Rama 2 Samut Sakhon) that I visited. The pricing is usually cheaper compared to buying from a gift shop ….. but it is mass produced and not individually handcrafted item.
