Why the handle changes the whole cup
A cup is a small sculpture that has to work in the hand. Its handle changes balance, grip and the way the rim meets the drinker. Those decisions become clear through repeated making and testing.

Start with the body
Look at the cup’s volume, wall thickness and centre of weight before attaching a handle. A narrow cylinder and a generous bowl need different relationships between hand and vessel. Sketch the handle in profile, but also imagine the space your fingers will occupy. The negative space is part of the design.
Test more than one grip
Some people use one finger, others two or three, and some support the body with their other hand. A studio prototype can reveal uncomfortable pressure points that are invisible in a photograph. Test only suitable finished pieces for hot drinks and follow the maker’s use guidance. A decorative form is not automatically intended for food or heat.
Let the detail belong
The attachment points should feel related to the body rather than added as an afterthought. A thick join may suggest generosity; a finer connection may feel lighter. Keep notes on each prototype so the next version answers a specific question. The successful handle is often the one you stop noticing after the first few sips.
