Hahah I feel so stupid asking this but I feel like I'm missing something really simple here.. When I use my half pad which sits directly underneath my saddle with a second square numnah under that..the second numnah always moves about and creases?! 

I attach the loops from my half pad onto the girth tabs either side and fit the second numnah underneath without attaching it to anything.. When I look at other people with half pads..their second numnahs seem not to move at all- they look really tidy lol. Whereas I look all folded and creased.

Am I missing something here guys? Both saddle pads fit.
