Thank you, @b15erk .  I did think about unpicking a bit of the embellishment, but they aren't bias so wouldn't work very well as binding.

I might even try and cut some of the mesh on the bias and try using that, but first I'm going to cut a spare piece and try the overlock and turn in method I think.  If I alter the differential feed on the overlocker to very very slightly pull the edge in, then maybe it will sit flat when I turn a hem in.  Oh, no, thinking about it, that won't work, I'd probably need to stretch it a tad, or not, I dunno now!

Crikey, that looks fun, not!  Good luck 

Ok, I'll ask, what is a singing bowl?

Pleased to hear you've fixed it, and this thread may well prove useful to someone else with  similar problem.

Linky - a good source for stabiliser.

If you only want small bits, I think I have a few I can send you.

@Bill What brand are your hooks?  How about looking for old tatty panniers on ebay to re-use hooks off them?

@RosyPosy Yup, Poppy and Sasha, both standard poodles, Poppy is quite big, and Sasha is a bit on the small side, she's often known as our sub-standard poodle
