1. Why the covering sheet matters
A covering sheet sits between the heat source and the beads and does three jobs: it spreads heat so no single bead takes the full contact temperature, it stops molten plastic from touching the soleplate or platen, and it lets you see how far the beads have fused as they turn translucent.
Get the sheet wrong and the failure is immediate and visible — residue on the surface, beads sticking to the paper, or an uneven finish where some beads melted flat and others barely joined.
2. Parchment paper (baking paper)
Parchment paper is the most widely available option that works. It carries a silicone coating rated well above normal ironing temperatures, so it stays stable, releases cleanly and can usually be reused several times before it browns and stiffens.
- Bleached or unbleached both behave the same
- Avoid anything sold as “non-stick paper” without a stated heat rating
- Cut sheets larger than the pegboard so the edges never lift into the iron
- Replace once the sheet is brittle or heavily discolored
In the UK and much of Europe it is sold as baking paper; in the US, parchment paper. They are the same product.
3. “Wax paper” means more than one thing
This is where most of the confusion sits. Several translucent, slightly slippery sheets get called wax paper in everyday use, and only one of them is a problem.
| Sheet | Coating | Use for fuse beads? |
|---|---|---|
| Baking parchment | Silicone | Yes — the standard household option |
| Silicone release paper | Silicone | Yes — thinner and more transparent than parchment, common with heat presses |
| PTFE / Teflon sheet | PTFE-coated glass fiber | Yes — the usual choice for repeated press cycles |
| Grocery-store wax paper | Paraffin | No — paraffin softens far below fusing temperature |
If you have watched someone run an automatic fuse bead press with a translucent sheet between the platen and the baking cloth, that sheet is almost certainly silicone release paper or a PTFE sheet rather than paraffin wax paper. It sits closest to the heat source, which is the one position paraffin could not survive.
4. Dedicated ironing paper and heat-resistant cloth
Purpose-made fuse bead ironing paper is thinner and more transparent than parchment, which makes it easier to judge fusing progress, and it typically survives more passes before it needs replacing. Heat-resistant cloths and mesh sheets work on the same principle and suit heat presses, where the sheet stays in place for repeated cycles.
For a retail customer making occasional projects, parchment from the kitchen drawer is entirely adequate. For a studio, a workshop or anyone fusing daily, dedicated sheets are worth stocking because the cost per project is lower and the results are more consistent.
5. What not to put between the heat and the beads
- Paraffin wax paper — softens below fusing temperature, smokes and leaves residue
- Aluminium foil — conducts heat unevenly and can scorch beads in patches
- Plain printer or copy paper — no release coating, so beads bond to it
- Cling film or plastic wrap — melts on contact
- Nothing at all — molten plastic transfers straight onto the soleplate or platen
6. Fusing without melting the design
Two setups are common, and they call for different habits. A household iron is controlled by hand, so you judge by eye as you go. An automatic fuse bead press runs a set temperature and time, so the judgement happens once, when you dial the settings in.
With a household iron
- Medium heat, no steam. Steam adds moisture and uneven heat; dry heat is what you want
- Keep the iron moving in small circles rather than resting it in one spot
- Work in short passes and lift the sheet to check rather than guessing
- Stop while the bead holes are still visible. Translucent edges with open holes is a fused piece; closed holes is a melted one
- Let each side cool before turning the piece over
With an automatic press
- Dial settings in on a test piece first, then keep them fixed — consistency is the whole advantage of a press
- Follow the machine manual for temperature and dwell time; these vary by machine and by bead thickness
- Leave the release sheet in place between cycles rather than replacing it each time
- Recheck the settings when you change bead color batches or project thickness, since both affect how heat is absorbed
- Judge by the first piece of a run, not by watching each one
7. Why finished pieces warp, and how to stop it
Warping is caused by uneven cooling. The fused surface contracts as it cools, and if one side cools faster than the other, the piece curls.
The fix is simple: leave the piece flat and put a light, flat weight on top — a hardback book over a sheet of parchment works — until it is fully cool to the touch. Cooling on a soft or uneven surface, or picking the piece up while it is still warm, is what produces curled keychains and ornaments that will not sit flat.
This step applies whether the piece came off a household iron or an automatic press. A press gives an even fuse, but it does not control how the piece cools once it leaves the machine, so the weight is still needed.
8. One side or both?
Fusing one side leaves a design with a flat face and a textured face, which is fine for magnets and anything mounted against a surface. Fusing both sides gives a stronger, more rigid piece with a uniform finish, which matters for keychains, ornaments and anything that will be handled.
The second side needs less heat than the first, because the piece is already partly fused. Applying the same time to both sides is a common way to lose the bead holes on the second pass.
9. What retailers should stock alongside beads
Covering sheets are a small line item that prevents a large number of disappointed first attempts, which makes them worth carrying even at low margin.
A workable stock position is dedicated ironing paper as the add-on sold beside beads and pegboards, with clear guidance for customers that kitchen parchment is a valid substitute and paraffin wax paper is not. JoyBeans Craft supplies beads, pegboards, storage, hand tools and ironing paper, but does not supply irons or heat presses.
10. Frequently asked questions
Can you use parchment paper for fuse beads?
Yes. Baking parchment is the most common covering sheet and is rated well above normal ironing temperatures. Cut it larger than the pegboard and replace it once it becomes brittle.
Can you use wax paper for fuse beads?
It depends which sheet is meant. Paraffin-coated wax paper from a grocery store is not suitable. Silicone release paper and PTFE sheets are often loosely called wax paper and are perfectly suitable; they are what most heat presses use.
What is the difference between parchment paper and wax paper?
Parchment is coated in silicone and is heat-stable; true wax paper is coated in paraffin and is not. They look similar and are shelved together, which is why the names get used interchangeably.
What sheet do automatic fuse bead presses use?
Usually a silicone release sheet or a reusable PTFE sheet, sometimes combined with a baking cloth. Both tolerate repeated cycles at press temperatures.
What heat setting should I use?
A medium setting with steam turned off is the usual starting point, but it varies by iron and project. Test on a small offcut and stop while the bead holes are still visible.
Can the covering sheet be reused?
Yes, several times. Replace it once it browns, stiffens or stops releasing cleanly.
