Troubleshooting: Flat and Uneven Coils
Flat coils happen when you roll with too much downward pressure and not enough outward movement — the coil pancakes instead of lengthening. The fix is in the hand position: use the full length of your palm from fingertips to heel, keep pressure light, and focus on moving your hands apart as you roll rather than pressing down. If a coil goes flat, don’t try to save it by rolling harder — that compounds the problem. Set it aside and start a new one.
Uneven coils — thick in the middle, thin at the ends, or lumpy throughout — usually come from rolling only with the fingers or applying inconsistent pressure across the length. The coil doesn’t know you want it to be even; it responds to whatever pressure it gets.
Pro tip: When a coil goes uneven, don’t keep rolling and hoping it will even out. Instead: fold the coil in half, twist the two halves together, and start rolling again from the beginning. Folding and twisting redistributes the clay mass evenly and gives you a fresh, consistent starting shape to roll from. It takes 10 seconds and produces a better coil than trying to fix an uneven one in place.
