Ok, who loves yarn that's easy to work with AND easy to care for? Well I'm a big fan for sure. Especially when it comes to my cardigans I wear on the daily. I'm constantly going to my yarn coffin that holds my acrylic yarn stash and pulling out my favorites.
At the top of that very long list is Wander Acrylic Yarn from Furls! So when they sent me a box full of their new colors they've added to the collection, I may have ripped apart the box in pure excitement to see 😂
There were 7 new colors chillin in the box and I was insanely excited to see a bright, pumpkin orange color among them!
I had to create a cardigan from it. That was literally my first thoughts. This yarn has incredible drape, so perfect for wearables and is the kind of soft that's perfect for a cozy scary movie night filled with caffeine and snacks.

This pattern consists of many granny squares all seamed together using the mattress stitch. It's great for beginners and also perfect for a project to take on the go.

ASSEMBLING
Use these graphs as guides for piecing together the sleeves, front panels and back panel.




SEAMING
Using the graph above, lay out the squares for the part of the cardigan being worked on. Grab a yarn needle, color A, and seam together using the mattress stitch.
Once assembled, lay the front panels on the back panel, starting at the top corner attach the front to the back completing the body of the cardigan.
Lay the sleeves on either side of the cardigan body, attach with safety pins to keep in place, then again using the mattress stitch and starting at the top of the cardigan, attach the sleeves to the body.
Seam up the sides.
