Fabric & Craft Stores

Since 2016, Yaya has been working with JOANN to create a one stop shop experience for cosplay customers. From fabric to trims and EVA foam, JOANN has embraced the world of cosplay and become the leading US craft chain to cater to cosplayers, all with Yaya’s guidance and expertise.

Cosplay Trims

& Embellishments

Expanding upon the success of the fabric line, Yaya and Cosplay Fabrics created an exciting line of trims and embellishments geared towards cosplayers and fashion aficionados. The collection was released in February 2019 in JOANN locations across the US and features bold unique trimmings and adornments that will instantly spruce up a costume.

EVA Foam

Besides fabric, the most used cosplay crafting material is EVA foam. It has been Yaya’s dream to create high quality EVA foam suitable for armor and prop making and put it in stores so Cosplayers can grab them and work on their projects whenever they want to. Thanks to JOANN’s openness to carry this material in their 860+ stores nationwide, Yaya and Cosplay Fabrics we’re able to develop the Cosplay by Yaya Han EVA Foam collection which includes high density sheets in various thicknesses and accessories such as dowels and textured foam. Released in July 2019, the foam collection has been well received by the cosplay community and come in handy for many con crunching crafters.

Sewing Patterns

In 2015, Yaya became the first cosplayer to create a cosplay-centric pattern line. Under the McCall’s Patterns umbrella, Yaya has released over 30 patterns, available in craft stores worldwide. Along with her cosplay fabric line, cosplayers have come to rely on Yaya’s patterns as an essential part of their costume making process.

The success of Yaya’s collaboration with McCall’s bridged the gap between the geek fandom and the sewing industry, and has led to a surge of new cosplay materials on the market.

In 2019, Yaya teamed up with Dremel® to bring a Yaya Han collection of electric rotary tools to JOANN stores in the USA. Dremel tools are essential to cosplay crafting, such as for sculpting, sanding and engraving EVA foam, plastic, wood and other materials. Now they are easily available at a neighborhood craft store alongside paints, fabrics and foam, further strengthening Yaya and JOANN’s Initiative to create a one-stop shop for cosplayers.
