Constructing a One-Piece Shirt Collar

1. Cut out an Upper and Under Collar (make sure you include the notches)

2. Cut out interfacing ( 1 piece, this should be the same as the under collar minus the seam allowance)

3. Iron on interfacing or use a glue to hold it in place (you can use a fabric pencil or chalk to mark the position of the  interfacing on the wrong side of the under collar)

4. Stitch around outside edge (leaving the neck edge open!) with a 1cm seam allowance, pivoting at the corners with the needle in

5. Trim the corner seam allowances back, make sure not to get too close to the stitching
6. Turn in the right way, and gently push the corners out
7. Press flat
8. 5mm Top stitch around outside edge
9. Your collar is now ready to attach
