What It Is
Meg's 'rule of one': sell one product (t-shirts), to one niche and audience, on one platform, and ignore mugs, hoodies, totes and other add-ons. Put the variety into designs instead, publishing as many quality designs as you can on that single product, because a few winners usually carry the store. The idea is that design skill builds up when you stay on one product, so in time you can judge a design before it goes live.
The Pitch
She says her brand did over $2.8 million in sales and $400,000 in net profit in 90 days selling only t-shirts, and that 19 of its 1,900-plus live designs drove more than half of those sales. She uses Steve Jobs cutting Apple to four products in 1997 as the model and compares the approach to digging one deep hole for gold instead of five shallow ones.
Who It’s Best For
People who tend to spread themselves thin and do better committing to one thing and repeating it.
The Truth (as we see it)
Focus is sound advice for beginners, and her point that a few designs carry most sales is common among print-on-demand sellers. Her revenue and profit numbers are her own and unverified, and getting to 1,900 designs took a team, ad budget and several years. 'Going wide' on designs still means paying to test them, which she doesn't cover here. The video promotes her free 12-hour YouTube course.
