You first need an insert template. I made my insert template by welding a rectangle to a circle in Cricut design space. Then I cut it out of paper and then put it inside my ornament. I adjusted it a few times until it fit how I wanted, filling as much space as possible.
Next cut the design you want to go on it from vinyl. I did a few Let it Snows and Merry and Bright for the gifts I gave but I also made Teddy one with the year on it and I just love how that turned out.
Size the message/image so that it is a little bit smaller than your insert piece.
Cut out of vinyl.
Weed out the negative space so you are left with just the vinyl design and paper backing.
Apply transfer take to lift the vinyl up exposing the sticky side.
Transfer to the insert piece making sure that the rectangle is pointing up. This is your handle so to speak.
Remove the transfer tape.
Next remove the metal part of the ornament and gently roll the insert and slide it into your plastic ornament.
How to get the snow into Using a funnel or piece of paper rolled into a cone pour in a few foam balls. Heads up this is the most time consuming part. Those stinkers are so staticky they are kind of a pain to get in there but trust me it's worth it.
Replace the metal hanger of the ornament and add a bow or tie of ribbon.
