We’ve made this very simple garment in lightweight towelling fabric, but you can also use T-shirting fabric for a summer bathrobe. 
 
Whilst making it, you will learn how to attach a roll collar and use bias binding around the edge of the garment as a decorative feature. You can use an overlocker for side seams, neckline, and armholes. If you don’t have an overlocker at home, you can use a sewing machine and finish the seams with bias binding. Intermediate level.
