Nothing wrong with your dad’s obsession. Very trendy of him to want to renovate and recover lots of armchairs.
My Dad is constantly redoing parts of my house, adding on extensions, cutting up kitchens and shifting furniture around. I was sitting at my laptop the other day planning on doing some observational drawing, but I wanted to create a series of drawings rather than a one off. I then realised I was surrounded by 4 arm chairs, and that was just in the room I was sat in.
My Mom’s hairdresser, who comes to our house to do my mom’s hair, always loves to see what chair my dad has bought next. I must say there’s also a rug obsession as each sofa and chair seems to have a rug to snuggle up into. My house is very comfy … So here is my rendition of the first 3 arm chairs … there will be more to come !
