Hey Roseviolet,
That's really useful, thank you .. just looked at the post you mentioned, d'oh, sorry I rehashed an old question! I thought I'd looked through most of them but I somehow missed that one, which is identical to what I was asking, I didn't mean to be that lazy!
Thanks for pointing me in the right direction, I was very close to just buying a doughnut cushion 🤣 shows what I know!
I'm glad your op went well and you had a good recovery tho 👌👌
FF 😊
