Finally managed to finish my slate frame bag today – but it took most of the day again! First I attached the shoulder straps to each side of the bag – making sure they were at the same distance, and of the same length, on both sides. Then I pinned and sewed on the lining to the top of each side of the bag.
Once the lining had been attached to both sides – the two sides of the bag are opened up and the right sides placed together. I then stitched these together leaving one end (lining end) open. Then bag was then turned in the correct way before stitching the lining to the base of the bag. I then topstitched around the top edge of the bag to keep the lining in place.
And there you go – a weekend of sewing and a functional bag to boot. It is very large, not very pretty, especially with the off pink bedsheet lining – but it will make my life a lot easier – and I doubt anyone would want to bag snatch it! The big plus though is that it cost a fraction of the price of the shop bought counterpart!
