How to write a sentence describing the complexity and triviality of work with needle and thread?

Sentences describing complicated and trivial work are described with needles and lines. For example:

1, work is like a tangled needle and thread, which needs to be handled one by one.

2. Every day's work is like sewing, which requires constant threading, busy and trivial.

3. Work is like a fine needle and thread, which needs patience and meticulous stitching of every link.

Needlework makes me feel a lot of pressure, so every little thing should be handled carefully.

Trivial things at work, like the screws on a needle, need to be tightened one by one. The above are some complicated and trivial sentences that describe work with needle and thread. I hope it helps you.
