I was recently inspired to try my hand at hand lettering a feature wall in my semi-refurbished dining room. Originally I was only going to paint it a darker colour and leave it at that, but inspiration struck and my (very) patient husband was happy to let me loose on it. I felt brave & didn't do any measuring or guideline markings - I just went for it... and I must say: I am quite pleased with the end result. The new round mirror that I found on sale certainly helps, but the hand lettering sets it apart for me.
It can potentially translate well to customised nursery walls with baby's name & date of birth, or even family rooms & kitchens - the possibilities are endless.
