After my stupid hiccough with the oven gloves and a few minutes undoing the stitching I was back 'on the case' as 'they' (whoever they are!) say.
First of all I sewed the edge of the lining along the main part and in the right place this time!!
Next I crocheted doubles through the two parts of the outer pocket and including the inner lining too. That was a bit of a struggle at times!!
I then found that I'd got enough odds and ends of cotton yarn left to add a stabilising couple of rows of double crochet to the joining part between the two gloves!!!
I've since tested them and they work a treat. All for the price of nothing!!! Some of that yarn by the looks of the label must've been almost as old as me - if not older!!!!!
