First a non-dust desk surface and tools below are needed (seen photo 2-1).

1. 1x scissors
2. A number of flat cables
3. 1x single-side adhesive 3J
4. 1x duct tape 3J (100mm )

To cut our and paste with single-side adhesive

First cut out 540mm-long single-side adhesive, similar to the length of the flat cables (Seen 1-2 1-3 1-4 ).

Second, tear the single-side adhesive, put on the desk surface, and paste the flat cable on it(Seen 1-5). Smooth adhesive is necessary. And then fold the flat cable to be pasted another surface (Seen 1-6, 1-7, 1-8, 1-9)

To cut out and paste with duct tape

First, paste onto the duct tape and cut out proper length (Seen 1-10).

Second, fold and paste from the middle part to the side. No obvious distortion (Seen 1-11).

Third, fold and paste the rest part. The total length should be longer than single-side adhesive to make it full covered (Seen 1-13). Photo 1-14 is not correct operation.

Fourth, pasting finished.

Fifth, be aware of safe operation.
Sixth, handle the waste properly.
