Regardless of your budget, there are always ideas that can improve your space. Start by recording your needs and finding your style and the next steps will be easy.
Make a plan
Keep a record of the work that needs to be done and the materials that will be needed. Market research will help you get an idea of the total cost to set your ceiling.
Find what suits you
Ideas can be obtained from anywhere (thanks to the internet). As far as the application is concerned, the most important thing is to have taken the right measures and not to fall out in the dimensions. Do not be disappointed if, from an aesthetic point of view, you do not fully achieve what you imagined and do not seek perfection. Perfection, after all, is boring, while a "mistake" gives personality to space.
Create a board
Use samples of fabrics or upholstery, photos of furniture, color charts, and floor lists to create compositions that will give you an idea of the final look of each room and help you make decisions. A cork bulletin board is an ideal choice for your tests.
Keep a record
Once you have your preferences, create a folder with all the codes and model names corresponding to the stores where you made your purchases. You will find it useful if you need to repair something or make an addition in the future.
Take your time
It is good to have a schedule and try to stick to it (good luck with that!). But do not push yourself to complete the decoration of the space, in the smallest detail, at once. Once you are done with structural and functional elements, leave the decorations for later, gradually adding one by one piece.
