Hi, I’m new to sewing and reading a pattern for some pants with side pockets (Kwik Sew pattern 3701 – harem pants). I says to attach interfacing to one part of each pocket, but it doesn’t say which part, i.e. is it the part that will sit against the fabric of the trouser leg or is it the part that will sit against your leg? If I had to go by logic, I’d say the bit that sits against your leg as it probably has more wear and tear, but some advice very much appreciated. Also on the picture it looks like the bit of interfacing is not covering the whole of the pocket piece, but rather just along the seam, but the instructions mention nothing about the shape or size of the bit of interfacing.
