Collars can be time consuming at the best of times and I love garments with great collars. Why?
They frame your face, can draw the eye to your face whether sewn correctly and can make a garment fit in with other jackets/vests that you have in your wardrobe.

So the main advice I can give is:
– use directional stitching to keep each piece balanced
– interface both sides of a collar to keep it looking crisp
– invest in good ironing tools and steam iron

The collar above was part of the Butterick 5328 wrap shirt that I finished last week. Do I take notice of notches? Not unless it’s a coat or jacket. This shirt was made with cotton quilting fabric and it leant itself to using armoweft.
