Tetra snuggle Bed cover

Hello

I am new to this forum and am looking for a little bit of help.

I live in the UK and have got a tetra snuggle bed that I bought about 3 yrs ago. I really need a new cover for it but because the bed is practically unheard of in the uk it is impossible to get a cover.

I would like to make a new cover for the bed myself but wondered if there was anyone out there who had made a cover or knew of someone who made a cover. I would like a pattern so I can do it myself.

I have already spent hours trailing the web trying to find either a pattern or new cover but the cost to have one shipped to me is too expensive.

would appreciate any advise.

thanks in advance
