Single Line Valentine Card Bundle. This bundle contains 12 Valentine card designs to make quick & easy cards to always have on hand. 10 designs come in 2 sizes to fit 5×7 and A2 cards and 2 designs fit 5X5 cards. These single line designs are just that – made from one single line and perfect for using with a foil quill, engraving tools, sketch pens or Cricut foil transfer tool. These are not made for cutting. The final thickness of the design will depend on the size of the tip or nib of the tool used. I have included a png file with these but it’s really just for viewing purposes. It’s not for tracing as that would create double lines so be sure to use the correct file your machine such as the SVG, DXF or EPS file.
