I have mastered the tiny corner hems quite nicely.  I suppose I don’t really have to add a tiny hem as the vinyl backing make the fabric non fraying – but they are dogs and I think it will make it wear better – and it looks neater.

And I have discovered that if you peg round the front straps with seam pegs and let it rest for a bit – it helps the fabric curl a bit.  I have really taken to these little pegs.  They have one shaped side and one flat side.

AND – before you ask – yes – I did try to use ordinary pegs – but they were too big and cumbersome – and the flat side on the special ones means you can get them right up close to the machine foot to sew.
