Stirrup bags making diy
Stirrup pouches are designed to protect the saddle, you can put them over the stirrups when you're not driving.
You can buy these bags, of course, but they are quite expensive and very easy to make from a soft fabric. I made cheerful stirrup bags out of a fleece fabric with hearts of an old dressing gown.

what do you need:
1. two pieces of soft fabric of about 34x 15 cm
2. elastic with stopper
