Paint roller left fuzz all in my paint job?

how do i fix it without stripping the paint and starting over?Paint roller left fuzz all in my paint job?
Definnitley lightly sand the walls to remove the ';Fuzz'; and buy a knew roller sleeve, but always always, whether its a good quality or lesser quality roller, rinse it thoroughly in clean cold water, squeeze out the excess water and let it dry out before using, all paint roller sleeves have some loose material in them just from manufacture so they all need to be cleaned before use.Paint roller left fuzz all in my paint job?
If it's not really bad, I would just give it a lite sanding to knock of any noticeable hairs. Buy a good quality roller and apply another coat. Another thing is to take the new roller, pullout a piece of 1 1/2 or 2in. masking tape and roll the roller over the masking tape back and forth against the sticky side of tape to remove any loose hairs on the roller. When apply paint be sure to keep the roller wet!. A dry roller is obviously going to help pull unwanted hairs from the roller itself.
get a better quality roller and give it another coat, no need to strip off the paint
