Various people are saying it's a pyramid scheme and therefore a con. I don't see it myself. A pyramid scheme generally doesn't have a physical product and crucially requires a number of tiers recruiting new members. Origami Owl just appears to be a straightforward direct sales model akin to Tupperware or various cosmetics parties (e.g. Avon in UK). The reps buy stock, arrange the parties and sell it. That seems to be entirely legit.
The second bone of contention is with the use of the word "designer" as a name for the sales reps. Hardly the crime of the century. Tupperware call their reps "consultants" but they don't charge consultancy rates. It's just in keeping with the theme.
I think we should be celebrating this young woman's initiative in seeing a market, finding a product that fits and building out the business.
