2. After all hollowing out, cut along the contour line of the edge. At this time, you can align the line with a steel ruler, cross it with a carving knife (this is easier to align, but it will slip if you can't hold the ruler with your hand), or you can cut it with scissors (it is easy to cut if your hand is disabled, but the operation is simple).
3. Finally, replace the carving knife with a needle, and make holes where necessary. Poke lightly, the small hole should be shallow and the big hole should be deep. Punch the hole at last, otherwise it will disappear once you press the hole.
4. Stick butter paper where you need to stick butter paper, cut it along the outline and stick white glue, or stick the whole piece with double-sided tape without cutting it, but double-sided tape will affect the light transmittance, so those with double-sided tape can only be stuck on the farthest side that will be blocked by the frame.
5. After all drawings are processed, assemble the plastic frame. After the four corners are installed, you can put them on the desktop to see if the four corners are on the same plane. Tear off the two layers of protective film of acrylic board and put it into the frame (remember to break off the small iron sheet for fixing around the frame before putting it into the frame).
Then according to the figures in the lower right corner of the drawing, from small to large, the figures face forward, the first one is placed near the acrylic board, and a plastic frame is placed behind it, and a drawing is placed. If there is more than one plastic frame, place two frames between the last drawing and the backplane.
6. Stick the lamp strip and the receiver on the back plate, connect the USB cable to the receiver after passing through the small hole, cover the back plate with the receiver on the top and the lamp strip on the bottom, and then break the small iron sheet back to fix the back plate. If you want to hang it on the wall, you should install a fixing pin at this time. Stick four anti-skid pads on the bottom of the frame.
