Here was my process. You can also check Cheri's instructions and see her beautiful shirts too.
I bought this super cute fabri from Karamat
This fabric is from I wanna be a cowboy collection by Riley Blake. I love designer fabric but never have the money to spend on it. Tammy from Karamat has good prices for desinger fabric and I decided to splurge a little for thier birthdays. I made three of these shirts with one fat quarter.
Lay your polo out and trace the shape out on heat bond.
I used a plate to help with the yoke part of it. Once you have traced the back and front yokes, iron it on the wrong side of fabric. Then cut out the yokes, place on shirt and do any trimming to make it fit best. Peel backing off and iron down.
Next I sewed a straight stitch around the yoke. I like the frayed edges so this worked perfectly.
My shirt looked sloppy at the shoulders so I used Cheri's suggestion to cover this and it gives it a nice finished look. I used some brown swiss dot fabric ironed into a little tube and stitched it at the shoulders.
Then I put on my son who was thrilled with his BIRTHDAY SHIRT.
