Two cushion covers

I have had a piece of upholstery material for 14 years now and finally want to get round to doing something with it!

It is only big enough for two cushions but I'd like them to be as large as possible. I have looked at cushion pad sizes and the most appropriate size I think is 61cm x 51cm.

I would need the cushion covers to be nicely finished on the inside as well as the outside.

The quote should include the cost of posting the covers back to me once completed.

Thanks.
