Thanks everyone for your lovely comments, my DH has just made a dowelling frame for handing it...I haven't made a typical hanging sleeve, I found on the net a simple way of making triangle pockets on each corner, you can slip doweling into each corner and it keeps it perfectly square!!
I am going to start a new post with some pictures so I can share the technique incase some of the newbies like me find it easier!! :D :D
