It's important to press the fabric well before you begin. You don't want to attach wrinkly fabric to your clock face.
Now, set your fabric aside for a moment. Lay the plastic cover on top of your interfacing/stabilizer and trace around it with a pen or pencil.
Now, cut out your circle, leaving a bit of extra space so that later you can cut the interfacing and fabric together for more perfect edges.
Lay your fabric down on your ironing board with the right side facing DOWN.
Then, lay your interfacing on your fabric with the shiny/adhesive side facing the fabric.
This is your opportunity to place the pattern of your fabric where you want it within your circle.
Just make sure one more time that the glued side is facing the fabric. It's a shame to get that wrong.
Now press it on well according to the instructions.
And cut your circle out!
You can cut it out with scissors if that's what you have. Really, that will be just great, especially since you have a nice line drawn.
But if you'd rather use a circle cutter, just measure the radius of the circle by placing your pin in the center of the clock and your blade at the edge of the white, then tighten your screw. (My cutter isn't quite aligned in this photo.)
Really, if you're using the circle cutter you can skip the tracing step. Just find the approximate center of the fabric and interfacing (doing a quick dry-run to make sure you won't go off the edge anywhere) and cut that bad boy out.
This is your last chance to press, so really make sure any puckers are out of it.
Now, using a ruler or your cutter or any wildly creative method you'd like, find and mark the center of your circle.
From the center of the circle, cut a line to the edge. Do not cut your circle in half! Also, this is another chance to get picky about pattern placement if you want to. If you'd like your seam to point to the six (go straight down), consider how that will affect whatever is going on with your fabric and cut accordingly.
Now, find something small and circular. Maybe 1/4"-1/2" in diameter.
Place it in the center of your circle and trace around it.
Cut out that little circle carefully with scissors.
Now you get to slide your pretty fabric easily onto your clock face to make sure your fit is right. Feels good!
Once you've checked to make sure it fits properly, you can take it off for a minute to put some double-sided tape on the face.
Lay some tape about every two to three hours (ha!) taking extra care to put tape all along where the seam will be.
Now just slide your fabric into place and pat it down so it's sure to stick well to the double-sided tape. Smooth out the seam to conceal it as best as you can.
Pop the cover back into place.
Now all you need is the correct time and a AA battery and you're good to go!
Pretty and easy!
So pretty and easy in fact, that I did a yellow one too just for kicks! (My seam wasn't awesome here. The truth is, the yellow one was my first one before I decided to do a tutorial. Live and learn. And y'all get to learn from my mistakes to give the seam lots of tape!)
