From Elbe Textiles:
Today I am providing the dimensions for a basic, zero-waste robe pattern.
I had originally called this a fauxmono, as I was inspired by the zero waste pattern elements of a Japanese kimono, and my version was a bit of a bastardization. But I am conscious of cultural appropriation and will stick with calling this a robe.
For the record, this picture below isn't an exact replica of this pattern - the silhouette and measurements are the same, but I have used 3 different types of fabric in my version as I was trying to use up leftover fabric I already had in the house. Because of this, there is a seam halfway down my sleeve where two different fabrics meet, that is not on the pattern provided.
Buuuut, the way this pattern is set out - you can totally use 3 different lengths of fabric and it will still be zero waste (as long as your fabrics are all from a 140cm wide roll). This is what you'd need if you wanted to use 3 different fabrics.
Fabric 1: Main Body (80cm)
Fabric 2: Sleeves and Lower Front/Back Panels (80cm)
Fabric 3: Sleeve Hem Band, Neck Band, Pockets, Underarm Gussets (30cm)
