Piping thin then thick: how to get an even bead

The bead swells and shrinks along a line or ring.

Fix a mistake Updated

Quick answer

A likely cause is squeezing harder and softer as your hand gets tired or your grip changes. The fix: keep the same squeeze and the same speed from start to finish, following the pacer.

What it looks like

  • A line has fat blobs in some places and thin stretches in others.
  • A rosette or ruffle is fuller on one side than the other.
  • Corners of zigzags pile up while straight parts look thin.

Likely causes

  • Squeezing harder and softer as your hand gets tired or your grip changes.
  • Changing speed: slowing down makes the bead fatter, speeding up makes it thinner.
  • Pausing at corners while still squeezing.
  • A bag that is overfilled, so warm hands soften the icing as you go.

How to fix it

  1. Same squeeze, same speed

    Keep the same squeeze and the same speed from start to finish, following the pacer in the ghost-nozzle guide.

  2. Keep corners moving

    Turn the tip at a corner without stopping, or ease off very slightly as you turn so the icing does not pile up.

  3. Fill the bag about half full

    A smaller amount of icing is easier to squeeze evenly, and your hands warm it less.

  4. Refill before it runs low

    When the bag gets low you squeeze harder without noticing. Top it up or twist it down before starting a new row.

Where it shows up on our sheets

It is most common with line, zigzag, loops, rosette, scrolls and ruffle. These sheets have strokes where the scorer looks for it first:

How Icing Coach spots it

Icing Coach measures how wide your bead is all along each line and ring. The more the width changes, the lower your evenness score; the stretch that varies most is marked as a zone.

Every score uses the four corner markers on the printed sheet to flatten your photo onto the template, so it compares your icing with the exact shapes you piped over. How the score works.

Sheets to practise it on

These have the scrolls, ruffle, zigzag, loops where it shows up most. Pipe one, score it, then pipe it again and compare. You need tip 21, tip 104 or tip 3.
