I definitely feel similarly about bad instructions. I have found a few recent products that actually had good instructions which made me really understand the issue.
Good instructions give a single possible interpretation. Bad instructions could be interpreted to mean mutually exclusive things.
Does the washer go on the bolt before the bolt enters the hole? Or on the other side? If you get it wrong you may not tighten it correctly and may compromise the strength of the furniture.
I recently bought and built a few items and they had clear, unambiguous instructions. Only one possible interpretation, clear logical steps, and well labeled parts. One was from GiantX and the other was Fantastic Furniturea chain here in Australia. The difference between those and other flat pack items was insane.











When you get it wrong, which you will, just correct and move on. Make a separate acknowledgement that you will make mistakes but your intention is to get it right. Make those two separate things, don’t make the moment of you getting it wrong the time you affirm your intent, keep them separated and they will both be more effective.
Also, ask them if they would like to go clothes shopping, in person or online, and support them in trying things that they have not yet been comfortable trying.
Being supportive isn’t about perfection. It is about effort. Your effort shows your care and consideration which in turn show your love and regard. Be there, be involved as is wanted, and be willing to accept making a mistake as you learn together. That is worth more than any amount of perfection that cannot be provided. Remember, the effort is the display of love, messing it up is something that happens along the way, keep trying and things will work out.
