In my practice I customize and tailor everyday items to fit a clients home and lifestyle. Often, one size does not fit all- as we know with clothes, shoes,.... glasses (loads of things around us) need either tailoring or "breaking in"
Nips, tucks, extensions.... all part of the design process.
I've seen clients get disappointed with products or placement of their items or purchases they make themselves - not realizing the need for tailoring and customization.
Sometimes things are "plug and play"... not so much with other accents.
Scale, texture, color, and well being customizations are important.
Life changes and surroundings require maintenance and upkeep. (often) So do we!
