my advice would be - get the big furniture pieces first, because in the end they dictate the general vibe and design of your space, and compliment them with smaller pieces like lamps rugs etc. also, try to think ahead a bit and DONT buy trendy furniture. don’t go overboard with color because you WILL get tired of it. remember, people are most comfortable in spaces and colors resembling nature the most. ahhhh generally take it slow? i understand the excitement about furnishing your space but finding your style take a lot of time. and if you have the resources try to invest in good quality furniture!
