Overlock the top raw edge of the pocket
Check the pattern for the placement of the fold line at the top of the pocket. Here the fold is 2.5 cm from the raw edge.
Sew down the folded section at each side along the seam allowance (here I'm using 1cm)
and the other side (I like to see where the folded piece finishes)
Progress so far ...
Trim the threads and a little of the folded edge inside the seam allowance, just a little diagonal cut.
Turn the right way out and press, making sure the top corners are sharp and the centre of the fold is 2.5cm deep.
Using a long stitch mark the seam allowances around the edge of the pocket. I just sew 4 straight lines, so I don't have to worry about turning corners accurately with a long basting stitch.
Use these lines as a guide while pressing the seam allowances under
I like to stitch along the top hem at the edge of the overlock stitches, here I can see it is at the 2cm mark on my machine. Don't stitch yet!
Turn the pocket over so that the right side is facing up. I've changed the top thread to a contrasting orange for top stitching. I lengthen the stitch slightly from 2.5 to 3 on my machine. Sew a line 2cm from the top.
Here's the pocket ready to sew on to the back of the jeans.
I'll post more pictures next sewing/computer session
Happy to answer any questions :-).
