Help needed, making fine lines
I'm new to oil painting and I'm having a really hard time making fine lines.
I bought round and pointy hog bristle brushes in order to do some linework on a painting, but the bristles are rock hard because they're glued together when they're brand new so I went ahead and used some water to remove the glue from the bristles and the brush turned from a fine liner-looking brush to a round mop and became completely useless to me.
I've searched information about this for days and watched a bunch of videos but nowhere have I seen any mention about removing or not removing this glue from new brushes, other than on a Finnish brush brand's website about a type of Japanese sumi brush of which stem you're apparently supposed to leave "starched" (hardened with a starch based substance) and only moisten the tip of the brush even when cleaning it.
Can anyone answer how I would go about making fine lines? Or how I could get a pointy brush since none of my brushes are even remotely pointy and they're only capable of making a really fat and ugly line, thanks
