You Make Beautiful Things. Writing About Them Shouldn't Be the Hard Part.
Time Drain
Every hour spent guessing the right keywords is an hour taken away from creating.
Platform Exhaustion
Formatting tags for Etsy, then rewriting them for Amazon, then again for Depop — that's not why you started your shop.
Blank Page Paralysis
Staring at a blank description field when you already know your product inside and out.

Etsy
“Handwoven from sustainably harvested seagrass by artisans in our small coastal workshop, this basket brings warmth and texture to any space. Each piece has its own character — subtle variations in the weave pattern mean no two are exactly alike. Use it as a planter, a catch-all for your entryway, or a cozy home for your favorite throw blankets. Measures approximately 12" diameter x 10" tall with sturdy reinforced handles.”
