The rule is to never put anything in front of or near a baseboard heater. A key thing here is not to obstruct the natural air flow. air has to flow across the floor to the heater and then up the wall. Baseboard heaters are a pain for space reasons and efficiency reasons.
Place furniture and draperies 6 to 12 inches away from baseboard heaters. Baseboard heaters are generally safe, if they are maintained properly and used correctly. Placing furniture too close to baseboard heating can be a fire hazard and damage the heating system.

According to the Holyoke Fire Department, a recent fire started with combustibles too close to the baseboard heater. If objects are too close it doesn't help with airflow and creates a fire hazard under enough heat. Curtains for example that hang near or above a heater should not be touching the baseboard heater.
Even with proper space, a big, flat piece of furniture can still restrict air flow enough to stop the flow of air back into your HVAC system. Open or backless shelving may be placed in front of an air return vent, but do not drape any fabric on the shelves as that can get pulled against the vent due to the flow of air.
Refrigeration products are more likely to experience performance issues next to extreme sources of heat. Cooking products will operate properly, but could pick up residual heat from extreme heat sources.
If you rely mostly on electric baseboard heaters to heat your home, they probably make up a big part of your annual electricity bill – sometimes as much as 44%. However, there are plenty of ways to maximize the efficiency of your baseboard heaters to cut down your winter heating costs.
don't put furniture directly in front of your heater - leave a gap of at least 30cm (or around 12 inches) if there's a window above your heater, don't let curtains hang too close to the top of the heater - leave a gap of at least 7.5cm (or around 3 inches)
When there's no heating on, you can have the drapes in front of the baseboard heaters all you want.

Generally speaking, electric baseboard heaters are safe when installed correctly and kept far away from any flammable materials. Exercise caution if you have children or pets in a home with electric baseboard heat. These become much hotter to the touch than hydronic and burns can result.
Drapes, furniture, and other combustible materials should be at least 6 inches away from each side of a baseboard heater. As noted, most baseboard heaters are designed so that their ends can touch baseboard wall trim, but this applies only to the very ends of the heater unit.
Maintain Clearance: Keep furniture at least 6 inches away from baseboard heaters. This prevents the blockage of heat and reduces fire risk. Avoid Flammable Materials: Do not place furniture with flammable fabrics or materials near baseboard heaters.
Allow 30 cm (12 inches) of clearance in front of a baseboard, 6 inches to the sides, and 12 inches above the heater.
Water is excellent at retaining heat due to its high specific heat capacity. When placed near a heater, water absorbs, and stores heat from the heater, helping maintain a stable temperature in the room.
Electric baseboard heaters have an on-and-off switch, but you can leave them running at a regular temperature setting.
Avoid flammable objects, too
Some manuals list curtains, papers, furniture, pillows, and bedding as objects to stay away from. The Association of Home Appliance Manufacturers (AHAM) recommends further precautions, such as keeping flammable materials like paint and matches far away.
DO NOT place heaters on cabinets, tables, furniture, or carpet, which can overheat and start a fire.
You can cover your baseboard heater with furniture, sure. But if you don't do this carefully, you might end up impeding the path of the heated air. This can reduce the efficiency of your heating. Paint is another option, but it doesn't last long.
You can create a gallery wall or simply hang a few decorative pieces to add charm to the area. Potted plants, decorative baskets, or other ornaments nearby also do a great job drawing attention away from the baseboards.
