Attach a Patch: Whip Stitch Method

Ingredients: Patch {This Instructable uses a patch that I make and sell}. Needle {Size 10 "Betweens" work well for attaching patches}. Thread {48" for a 2.75" round patch, thread doubled for extra strength}. Thimble {Make a Duct Tape Thimble if you need one}. Base Garment {This Instructable uses my son's hoodie}.

Step 1: Positioning the Patch

It's your patch, put it anywhere you want. But to place a patch over your heart, or in the standard Name Tag Zone: Find the midpoint on the front-facing sleeve seam. {See the thumb in picture}. Draw a guide line towards the center of the chest that is perpendicular to the [imaginary] zipper. Find the midpoint of that guide line. That's your center.
Pin it if you need to. 

Step 2: Securing the First Stitch

To prevent unraveling, secure the first stitch with a "back tack": Insert needle into base garment. Pop it back up, making about an 1/8" long stitch.  Pull the thread through slowly, leaving about a 1/2" tail.
Reinsert the needle into the same hole you started with. Pop it back up the same hole. {Go slow, accuracy counts}. Pull the thread through, holding the tail secure.

Step 3: Attaching the Patch

To attach the patch: Draw the needle up into the patch, as close as you can get to the inside of the border. Pull the needle through. The patch is now flush with the garment. Insert the needle back into the base garment, about 1/8" over from the exit of the "back tack."  Start each stitch as close as you can get to the edge of the patch.

Step 4: Whipping the Stitch

Continue stitching around the circumference of the patch. Keep your stitches evenly spaced, and fairly close together.  Finish with another "back tack" {see Step 2} through the backside of the base garment.

Step 5: Sporting the Patch

Enjoy!
