The Beginner Guide to Siser® Heat Transfer Vinyl

Welcome to the creative world of heat transfer vinyl! If you don’t even know the HTV basics, don’t worry. You will by the end of this post! I was a beginner not long ago, and I’m not going to lie, it was pretty overwhelming at first. HTV, CPSIA, weeder? What are these people talking about? Now that I’m fluent in HTV lingo, all I can think about are the thousands of creative project possibilities! Here’s a a list of tips and terms that will help any beginner start creating quicker.

Common Terms

  • Heat Transfer Vinyl (HTV) is a material that’s easily applied with a combination of heat, pressure, and time because of the specially formulated carrier.
  • Carriers are the clear, polyester backing on HTV often called the “shiny side.” There are pressure sensitive carriers, which means they’re sticky or tacky, and static carriers that are smooth.
  • A Digital Cutter is the machine that will take a plain sheet of vinyl and carve a design into it with a small, sharp blade. These range from wide/large format to desktop and hobby machines.
  • Weeding is the process of removing the extra material after a design has been cut out.
  • A Weeder is the stainless steel hook tool that allows you to pick out cavities and weed excess with ease.
  • Cavities are the centers of an image or text. Like the inner triangle of a capital “A”.
  • A Heat Press is the machine that sandwiches the vinyl and the material it’s being applied to while releasing heat.
  • Pressure is the amount of force used when you push down a heat press or home iron on top of the vinyl to adhere it to a fabric. It’s so important we wrote a whole blog post about proper pressure and even made a video!
  • Heat Transfer Pillows are used to correct uneven pressure. Uneven pressure can be caused by seams, collars, buttons, pockets, and so much more! A pillow can be used to raise the application area above those obstacles, or it can be placed under them to allow them to sink in and out of the way.
  • Heat Transfer Cover Sheets are used to protect your fabric from scorching under the heat and ensures the vinyl adheres to the fabric and not your heat press.
  • Multipurpose Paper can be used as a cover sheet or it can be used to store weeded designs for future use.


Tip #1: Always Mirror Your Image

Your design/text should appear backwards before it’s ready to cut. The only HTV that does not require you to mirror is our print and cut materials with an exception when it comes to ColorPrint™ Soft.


Tip#2: Place The Carrier Shiny Side Down For Cutting

The carrier is placed face down, so you’re cutting through the duller, adhesive side of the HTV. A good cut is achieved when you can see the cut lines on the carrier side of the material, but the carrier isn’t punctured or torn…basically anyway. If you want to know all the specifications for quality cut lines check out any of these posts: How to Cut HTV on Silhouette Cutters, How to Cut HTV on the Cricut Cutters, or How to Cut HTV on Brother Cutters.


Tip #3: Try the “Heat Press Trick” For Sticky Carriers

Heat up the lower platen on your press for 10 seconds. Lay your EasyWeed® (or any other HTV with a sticky carrier!) on the lower platen and weed your design. The heat from the press will slightly activate the adhesive and allow you to weed the design more easily! See the heat press trick in actionFor more weeding tips, read this post. 


Tip #4: Place The Carrier Shiny Side Up For Heat Application

In this step of the process, your design should look the way you want your finished product to look just with the carrier still attached. Your design should be in the correct direction and all words should be right-facing.


Tip #5: Use a Cover Sheet

A cover sheet of some kind (whether it’s teflon, multi-purpose paper, or parchment paper) is always recommended to be layered on top of HTV during application. It acts as a protective barrier between the direct heat and your garment. Also, it’s especially important to use a cover sheet when layering and applying on top of material that no longer has a carrier attached. Otherwise, you could end up with adhesive or HTV stuck to your heat press platen.


REMEMBER: Every Type of Vinyl is Unique!

While some share a variety of similarities, not all vinyl weeds the same, nor do they all require the same amount of time, temperature, and pressure. Double-check the product specifications to ensure that it is being optimally applied. You can find our suggested settings for each material under “Application Instructions” on every product page of our website. OR view them in the Siser North America app which is available for download in the App Store and Google Play.
