It's a great scrap buster too, just like most mug rugs. Though you still need bits big enough for the whole piece. You can use whatever printable shapes you want!
What you need:
2 (9"x7") pieces of main fabric for front and back
2 square pieces big enough for your shape facing
1 printed shape your desired size
1-2 pieces for the inside of the shape (I used one piece about the same size as my main)
about 1/8th yard for the binding
Trace your shapes on the facing pieces (here are some outlined shamrocks on google). Place them on your main front piece and arrange however you like. Pin Make sure you have the right sides together. I just used muslin for the facing.
Sew along your drawn line.
cut out the shape, making sure not to clip your seam, trimming points and snipping curves.
Turn the facing to the wrong side of the main piece. I used a super dull lead pencil, I imagine it would be much easier with a turning tool.
pin. Top stitch down. (you can assemble your sandwich before you topstitch so you are going over it less)
Sandwich your mug rug. First lay the backing right side down, place the batting on top, the top right side up with the cutout over your shape inside fabric (don't want any batting showing through those cut outs!
baste around the outer edge to help hold it in place. Quilt however you feel. I just doubled over my top stitching.
Admire the back and trim off the excess.
Enjoy with your favorite coffee or tea! Don't worry, mine is just regular coffee! ;)
