Ya'll. I. LOVE. PAINTER'S TAPE. Seriously. It's the best! I use it for so many things and often recommend it to clients as part of our design process (especially now in the days of virtual everything because I can't physically be there). It's my go-to for so many things because it won't damage your walls, floors, etc!
Need to visualize whether or not the size of the sectional you saw online is a good fit for your living room? Map out the dimensions on the floor/wall with painter's tape!
Want to see what that gallery wall you're dreaming of is really going to look like before you invest in a bunch of photos and frames? Painter's tape.
Need an easy way to hang wall decor? Take a strip of painter's tape the length of your piece and place it over your the hardware (make sure it's straight!), poke a small hole in the center of the tape where you would place your nail, remove the tape, place it on the wall where you want to hang the decor and mark it! Voila! Perfectly placed wall decor every time!
