Fastening duvets together? (nsfw)

[johnbuoy]

As it's got chillier it's time to get the autumn/winter duvet on. I'm trying to combine two 4.5 tog duvets together. They have fasteners but they are both, ahem, 'male'...iyswim.
Can I get a double sided female fastener to connect them?

Try large safety pins instead.

Why don't you sow poppers or stick Velcro on, it will be less effort than finding the appropriate sex of popper. I made a his and hers quilt using a 4.5 king and 4.5 single and some poppers. Saved my marriage I tell you :)
