Here is a handy hint to keep your paintbrushes nice and soft long after they have been purchased and constantly used!
Once you have cleaned your paintbrushes squirt a bit of hair conditioner into a paint pot and add some water. Add your paintbrushes and leave them in the mixture over night.
In the morning take them out and they will feel nice and soft.
This little tip extends the life of those poor over used paintbrushes!
