Furniture, Wood and Cabinetry Finishing - Avoiding brush marks

Is it possible to paint a piece of furniture using only a brush, yet still get a nice smooth result, ie-not be able to see brush strokes once it's done?
Ideally I'd just use spray paint, but no way in the house, and it's 20 degrees out. And a roller doesn't fit the contours well.
Maybe one of those foam brushes, w/no bristles?
Thx!

It is possible. You will need a top quality brush, paint, and sandpaper. Sand after the primer coat and between finish coats. Use a sanding block to give you a flat surface after sanding. You might need to thin the paint a tad to have it flow optimally. Some colors flow better than others flow unthinned. Make sure that the temperature of the piece and the surrounding air follow the recommendations of the manufacturer of the materials.

Allow sufficient time for each coat to fully dry, before sanding.

Practice makes a lot of difference in this task. My recommendation is that you might achieve better results early in the learning curve by using an alkyd paint. Except for the mess, trouble to clean up, and the smell; alkyd paints tend to flow out a tad better. If you are experienced painting with a brush, it won't matter so much.

Hope this helps.

Chfite's right, I just want to reinforce that you need a good brush to pull this off, a cheap one's going to disappoint you.
