Frosted Windowpane mosaic blanket crochet-along by Juniper & Oakes.

An 8-week mosaic blanket crochet-along starting October 12

Five sections. One cozy winter blanket. Crocheted together.

Picture a frosty window on a winter morning: crisp lattice panes, snowflakes tucked into every corner, and something warm to curl up under. That’s the Frosted Windowpane Blanket.

Over eight weeks, we’ll crochet it together one section at a time: two mosaic strips and three snowflake squares, joined with my signature envelope border that hides your ends as you go. A new section is released every Monday, with catch-up weeks built in, so you can finish in time to wrap up in it this winter.

What to Expect:

  • ❄️ A new section every Monday, starting October 12

  • ❄️ Five sections: two mosaic strips and three snowflake mosaic granny squares

  • ❄️ Joining + envelope border released November 16

  • ❄️ Two catch-up weeks (hello, Thanksgiving!) before our Finish Line Party in December

  • ❄️ Designed using Lion Brand Heartland in evergreen, berry red, and cream

New to Mosaic Crochet?

You’re welcome here.

The complete pattern includes full written instructions and mosaic charts for every section. Inside the Collective, each release also comes with a talk-through video, and you’ll have live Q&As and a whole community of crocheters cheering you on. There’s no rush to “master” anything. This CAL is about enjoying the process, one windowpane at a time.
