Valentine’s Day Shirt using HTV & the Knockout Technique

It’s the month of love, and I couldn’t be happier! It’s a month full of hearts, roses, and love of course HTV! If you want to make a special shirt for Valentine’s Day with HTV to celebrate, read on to learn how to use the knockout technique to layer heat transfer vinyl for a fun “loving” shirt!


ImPRESSED Vinyl in red and white
-teflon sheet (included in your HTV pack)
-cutting machine (I used a Silhouette Cameo)
-blank shirt
-home iron
-weeding hook or craft tweezers

STEP ONE: Prepare design in software

Open your software program (I used Silhouette Studio) and draw or import a heart shape. Then type the word “love” in a fun script font.

Next, you want to duplicate your text and slide it over for later.

Place your word over the heart where you want it to be. Now select both the heart and text and go to the modify window. Choose Subtract, and you’ll see the word cuts out pieces of the heart exactly where the word was. Magic, right!

Select all the parts of the heart, right click and choose “group” so that all the pieces are together. Now we have an awesome cutout heart where our white text will sit. This technique works great when you want to use more than one color of HTV without the bulk of true layering.

STEP TWO: Cut out HTV design

Once our knockout heart is ready, right click both parts and select Flip Horizontally. We need to mirror our designs since the machine cuts on the backside of the heat transfer vinyl.

Place your first color onto the cutting mat with the shiny side down.

Go to the cut settings window and choose the material we will be cutting. The Heat Transfer, Smooth settings work great on our heat transfer vinyl.

Load the cutting mat into the machine and let it get to work!

STEP THREE: Weed you HTV designs

After both the red and white parts have been cut, it’s time to weed! Begin by peeling off the corner of the heat transfer, leaving just the design.

Use a weeding hook or a pair of craft tweezers to weed out the little insides of the letters.

Continue until you weed both parts.

STEP FOUR: Press knockout design onto t-shirt

After weeding, it’s time to turn up the heat! Warm up your home iron to cotton settings with no steam. Iron out any wrinkles on the shirt, so we have a smooth surface to work with.

Place the first layer (red) onto your t-shirt where you’d like. You can move it around as much as you want until you add heat.

Place a Teflon sheet over the vinyl and press the design for 15-20 seconds.

Allow the design to cool for at least 1 minute and then slowly peel off the clear carrier sheet. If any part of the vinyl starts to lift off, place the carrier sheet and Teflon sheet back down and add a little more heat and pressure.

Now place the second layer (white) directly into the knockout space of the heart we created. It should fit perfectly!

Continue with the same steps, with the Teflon sheet and pressing for 15-20 seconds. Allow to cool and then peel off the carrier sheet.

The knockout technique is the perfect way to create a  layered look with heat transfer vinyl!

This is the perfect project to practice the knockout technique.  So grab some ImPRESSED Vinyl and create your own Valentine’s day shirt made with HTV to show off around town, be sure to tag us #impressedvinyl and share your creations!
