I began by printing out a capital "E" and "M" using Times New Roman font and bumping the font size up to about 550 to print on letter size paper.
Next, I cut these two letters out and traced their shape onto the felt to be cut.
I traced these letters onto the adhesive sheets and cut those to size as well.
Next, you have to iron on the adhesive and peel away the white backer sheet, so all that is left is the adhesive on your fabric. The adhesive is clear on the fabric.
Finally, I placed the felt letter onto the glue and ironed one last time...and that's it! Done!
