A fleece saddle cover for my off-side side saddle and a numnah for it too.
I emailed a seller on Ebay that sells fleece side saddle covers to ask if they would be able to make me one and received no response. How annoying, and it's not as if I have never bought from them before too! How hard would it to say "Sorry, we don't do 'em!".
The numnah is more trickier to find though.
I REALLY like Mattes numnahs as they are hard wearing and just look nice. It's cheaper to order them straight from Mattes as well and you can choose any color. They are thin too so don't get in the way of a properly flocked saddle. I wanted to order a few for my Manorgrove, a white one for dressage, a brown one for showing/schooling and a pink one just for fun. I don't think they do an off-side one though but I wonder if I emailed them and asked, if they would be able to make a custom one? I'd just order a pink one as I wouldn't be showing or doing anything fancy in my off-side saddle.
