That article is so true of what people think. If it were me, I would have encouraged my neighbor to "make her own". I would have had her choose a sample of the kind she would like to make, and given her a list of basic supplies and tools, the general range in cost for each, and where she can get them. I'm sure the start up cost for her first card would have put things into perspective.
Although I can appreciate the skill, time and special materials applied to those christmas cards, I still would not ever pay thousands of dollars to send one to somebody.
