Eureka !! It's finished !

The final Bauhaus pattern waistcoat , it's taken 2 test pieces , I've lost count of how many months ! and this was too small to start with until I realised on the original test I had used a 3/8 " seam allowance and had used 5/8 " on this !! so a re-stitch on the sides at 3/8 then undo the 5/8 seam and it fitted :-)
