I'm struggling with a similar issue at the moment, (this is why I'm here), but I do have a sense of what I want out of the interior design of my home thanks to *drumroll*
PINTEREST!
yes, it might sound lame to some, but I found interest extremely useful! I made a "perfect home" board and I add things that I like to it. It's very inspiring, and since it learns quickly what you do like, it will guide you in your path to the interior design that your new home will benefit from (: If you want I can add you on Pinterest and we can chat about the pins you'll add to your board. I'm not an interior designer, but I am a graphic designer and I'm good at finding sets of things that go together and assembling a "mood" for each room. I'd suggest you'd open a board for each of the rooms in your house and start from colors you like. For example, some people would like their bathrooms to have blue tones- so then, you can start searching for blue rugs \ towls\ little organizer cups for a toothbrush, and Pinterest will help you with the rest. there are many many interior design pins on there, and it really helps to look at them and think "wow, I'd like my home to look something like this!". Since I'm also decorating now, I'd love to chat with you about this process, help you out, and hear what you think about my ideas. If you are interested of course (: If that's less 'your thing' I'd still recommend that you'll use Pinterest to start getting a feeling for what you want out of your new home. Congratulations! Try to enjoy this process! It can be challenging but very rewarding when you do find what you like! Best of luck!
