The Master Fusing & Ironing Guide

Follow these time-tested techniques to protect your pegboards from heat warping and get perfectly even melts.

1

The Tape Method

Cover your completed bead piece with regular masking tape. Press firmly with a roller or scraper, then poke holes in each bead with a spare pegboard to prevent heat blowouts!

2

Remove from Board

Peel the taped design off your plastic pegboard. Never iron directly on pegboards for large projects—this prevents your pegboards from warping and ruining future crafts!

3

Gentle Ironing

Place parchment paper over the beads. Set your household iron to Medium heat (Wool setting) with NO STEAM. Move in small circular motions for 15–30 seconds.

4

Weight & Cool

Immediately place heavy books or a cutting board over the warm piece for at least 10–15 minutes until completely cool. This guarantees an ultra-flat, professional finish.

Recommended Temperature Settings
Perler Beads (5mm)Medium Heat (Wool/Silk)Melt slowly in circular passes
Hama Midi Beads (5mm)Medium-Low HeatHama melts faster than Perler
Artkal S (5mm)Medium-High HeatHigher melting point, very durable
Mini Beads (2.6mm)Low-to-Medium HeatRequires swift, gentle passes
