So, to help the others I made these (very basic & badly made) videos (one handed videoing while sewing, so you know... bear with me) to (hopefully) assist in adding the zip, using my VERY easy method & then add the facing (or lining if you prefer) to complete your skirt.
After writing that, I suddenly wondered about the origin of the expression 'bear with me' ... what would we do without the internet? I found this... QI (quite interesting): The "bear" here is the old verb "to carry". You are asking someone to carry a burden along with you, until you both get to the destination. Thanks Viola Yee :)
For some reason my videos will not upload here, so I have had to upload them to YouTube - uuurrrgggghhh. I hope no one else finds them as they were meant only as VERY basic sewing assistance for the class.
