One Seattle woman has quite a yarn to tell.

She was at the Goodwill in the 6400 block of Eighth Avenue Northwest in Ballard on Sunday when she purchased a packaged crochet kit to make animal hats, according to Seattle police.

When she opened the kit, there was a suspiciously heavy item encased in yellow rubber. It had an “odd odor” and “100%” written on the outside, police said.

The woman called 911.

Officers responded, took the package and later determined it was a kilogram of cocaine, police said.

The package was placed into evidence and police are investigating.

“The safety of our customers and employees is our first priority and it is our policy is to keep hazardous, dangerous, or recalled materials away from our stores,” a Goodwill spokesperson said in an email. “We do our best to identify and remove those items if they are found. Part of our processes is to maintain an up-to-date list of all recalled products and we train employees to identify and spot check for any dangerous items and prevent them from being sold in our stores.

“We strive to comply with the letter and spirit of all regulations on the sale and resale of consumer products and we do not tolerate any known failures to comply with the law. It is also our practice to cooperate fully with local authorities in any investigation.”

Correction: A previous version of this story listed an address in Seattle’s Greenwood neighborhood for the thrift shop. This was an error in the Seattle Police Department’s news release.
