How to apply iron-on vinyl to a shirt

Step 1: mirror and cut

Iron-on vinyl is cut from the back. The adhesive faces up on the mat and the shiny clear carrier faces down, so the design must be mirrored or the text comes out backward on the shirt. In Cricut Design Space, turn on the Mirror toggle for each mat on the Prepare screen. In Silhouette Studio, use the mirror option in the Send panel or flip the design before sending.

Place the iron-on shiny side down on a StandardGrip mat, choose the matching iron-on material and cut. Plain iron-on uses the fine point blade; glitter iron-on may need more pressure. Run a small test cut on new rolls. For machine and material specifics, use the cut settings finder.

Note.If the carrier is face up on the mat, the blade cuts the carrier instead of the vinyl and the design will not weed. Shiny side down every time.

Step 2: weed the design

Peel away the vinyl you do not want, leaving the design on the clear carrier. Start at a corner and use a weeding hook for the centers of letters such as a, e and o. Weeding is easier with a weed box: a cut rectangle around the design that gives you a clean edge to start from.

Check the design against light before pressing. Tiny pieces left inside letters will press onto the shirt. If weeding pulls the design off the carrier, the cut may be going too deep or not deep enough; see Cricut not cutting through vinyl.

Step 3: prepare the shirt

Place the shirt on a firm, heat resistant surface: an EasyPress mat, the platen of a heat press, or a folded towel on a hard table for an iron. Ironing boards are too soft and flexible for good adhesion.

Pre-press the shirt to remove moisture and wrinkles. Cricut lists a 5 second preheat for cotton with Everyday Iron-On; Siser lists a 2 to 3 second pre-press for EasyWeed. Moisture trapped in the fabric is a common cause of designs that peel later.

Position the design. A common starting point on an adult shirt is a few finger widths below the collar, centered. Our shirt decal size chart lists typical sizes and placements.

Step 4: press with the right settings

Place the design with the shiny carrier facing up. Cover it with a protective sheet or parchment if the vinyl maker asks for one. Press with the settings for your vinyl, blank and press. These are the published settings for two common products; if the label on your roll differs, the label wins.

• EasyPress: hold it still with firm, even pressure for the full time. Do not slide it like an iron.
• Clamshell or swing-away: set the pressure so the press closes firmly; most presses have a knob for this.
• Siser and EasyPress: Siser asks Cricut EasyPress users to add about 30 degrees to its listed temperature.
• Household iron: turn off steam and press section by section with firm pressure. Results vary because irons do not hold an even temperature. For other vinyls on an iron, start with the maker's preset and run a test on a scrap.

Step 5: peel the carrier

Hot peel, warm peel and cool peel are part of the instructions, not a preference. Cricut Everyday Iron-On is a cool peel: wait until the carrier is cool to the touch, then remove it slowly. Siser EasyWeed can be peeled hot or cold. Siser Glitter is a warm peel.

Peel at a low angle. If a part of the design lifts with the carrier, lay the carrier back down and press again for a few seconds. Siser suggests covering and re-pressing lifted areas for 5 to 10 seconds.

Why iron-on lifts or peels

Cricut asks you to wait 24 hours before washing a pressed Everyday Iron-On project. Turning the shirt inside out and avoiding very hot dryer cycles also helps designs last.

Choosing a press

A household iron works for occasional shirts, but a press gives even heat and pressure. Our guide to the best heat presses for T-shirts compares handheld and clamshell options, and EasyPress vs clamshell heat press explains the trade-offs.

Frequently asked questions

Is Cricut iron-on vinyl hot or cold peel? Cricut Everyday Iron-On is a cool peel: let it cool to the touch, then remove the carrier slowly. Other Cricut iron-on types can differ, so check the Cricut Heat Guide for your exact material.

How long do you heat press Cricut iron-on vinyl? Cricut's Heat Guide lists 30 seconds at 315 F with firm pressure for Everyday Iron-On on 100 percent cotton using an EasyPress 2, after a 5 second preheat of the fabric.

Which side of iron-on vinyl goes down on the Cricut mat? The shiny carrier side goes down, the dull adhesive side up. Always mirror the design.

Can I layer iron-on vinyl? Yes, with compatible vinyls. Press each layer briefly to tack it, remove the carrier, then add the next layer and give the full press at the end. Check the vinyl maker's instructions for layering.
