Prym, Farbenmix, Swafing and the Handmade Kultur magazine (read all about that here). They fit me perfectly and I am more than happy to share the pattern with you. The pattern is in size EU 39 but adjusting should be fairly easy and straight forward. If you print the pattern on A4 paper and set the printer on borderless printing, you'll get the correct size.
What you need:1 pair of espadrilles soles
not too thin cotton fabrics (1 patterned for the front and 1 plain for the heel and the lining)
soft faux leather
thick cotton thread
fabric fixation tape
How it works:Step 1: First, print, cut and transfer the pieces of the pattern to fabric the following way:
2 mirrored pieces of the sole inlay and the upper from the faux leather.
2 mirrored pieces of the front in patterned fabric (add seam allowance).
2 mirrored pieces of the front in plain fabric (add seam allowance).
2 pairs of mirrored pieces of the heel (add seam allowance).
Step 4: Now glue the faux leather uppers to the front pieces with textile glue following the instructions on the glue you're using. Let dry. The back side of the straps might be visible when wearing, so you might want to glue some faux leather to the visible areas as well.
Step 5: Place each two pieces of the heel right sides together and sew the two stretches on both sides of the half circle cut-out together. Turn and iron flat. On the right side, drape bias binding around the remaining stretches and then sew it on.
blanket stitch. Continue the stitch over the open stretches, too, to get a nice uniform look.
Repeat for the other shoe.
