I used the cardigan from New Look 6735 for a cardigan jacket to go with the striped trousers I made previously.
It will give a soft suit look with the matching trousers.
I did finish this using the New Home MyLock 134D after all, as Keith the local repairman was able to sort it out the same day. Perhaps it was the threat that I would use the Bernina 800DL instead to finish the jacket that made him so speedy (he previously had a shop which sold Janome machines and so has his favourites).
It has had a general service, a replacement needle plate and a refurbished knife and no longer makes a noise like a pneumatic drill. I wish I had taken it in for a service earlier in its life as things would have been quieter, but I am very happy about this.
