May the 4th Be With You – Product Spotlight: Glow in the Dark Heat Transfer Material

Did you know that today is International Star Wars Day?  May the 4th be with you (get it??).

With such a prestigious holiday , I just had to craft!  What better thing to make than an awesome, glow-in-the-dark sleep shirt inspired by the Empire Strikes Back Logo?

We’ve made heat transfer shirts before  (remember the coloring book shirts and the fun summer heat transfer projects)- but this was my first attempt at a “knock out” design (where one image is layered on top of another) and my first time using this awesome glow in the dark vinyl.


Unfortunately, I didn’t document the steps on how to make this design, but I did want to highlight the vinyl I used.

I used Silhouette’s Glow In The Dark Vinyl.  This stuff REALLY glows in the dark after just a few moments of “charging” in the sun.  In the daylight it looks like a pale yellow/green, but even in just a little bit of shade, it glows!


Glow in the dark vinyl works just like regular heat transfer material.  There is a dull side and a shiny side.  You want to make sure to REVERSE your design before cutting and then stick the shiny side of the vinyl on your mat.  Reversing your design is vital because you are cutting your image upside down.  If you don’t remember this step, you will have backwards designs!


The shiny side of the vinyl is actually a backing sheet which you do not want to cut all the way through.

To make this knock out design, I first used my Silhouette Cameo to cut the entire design out in black vinyl and then weeded (removed) all the excess vinyl around the design and anything that I knew was going to be glow in the dark.  I covered the design with a tea towel and ironed it on to my shirt.

Next I cut just the glow in the dark parts of the design out in glow in the dark vinyl.  I wanted to reserve as much of the glow in the dark vinyl as I could.  By not cutting all the way through the back of the clear transfer sheet, I was able to line up my glow in the dark vinyl with my already ironed on black vinyl.  I covered the entire design with the tea towel and iron on the glow in the dark portion of the design.



ust a heads up: Glow in the dark vinyl is a little harder to weed than regular vinyl because the patterns on backside of the vinyl doesn’t show the score lines like regular vinyl.  I found that having good light will help show the lines- a task lamp really helped with this step.


I would also recommend bringing the design up on your computer and using it as a reference on where to weed.  I used a Silhouette Hook Tool and a pair of tweezers to help weed this design.

Check out this other shirt I made too- how cool??


What do you think of this design?  Will you try your own knock out design?

May the 4th Be With You!
