RBD Block Challenge 2026 – Block 1: Four Corners

I always love the feeling of starting a new block challenge. There's a mix of excitement and calm that comes from choosing fabric and making those first few cuts.

For this year’s Riley Blake Designs Block Challenge!, I’m sewing every block using prints from my Thimbelina fabric collection with Riley Blake Designs. This line celebrates the magic of sewing through the eyes of tiny sewing fairies. It includes soft florals, sweet thimbles, tiny cottages, and playful sewing motifs in a dreamy pastel palette.

This year’s first block, Four Corners, was designed by the Lori Holt (@beelori1). The moment I saw the pattern, I knew it was going to be a solid, grounding start to this year's quilt. It’s a beautiful balance of movement and structure, and a great reminder that even small changes in layout can create strong visual flow.

Four Corners came together simply and gave me space to play with the Thimbelina prints without overthinking the layout. I found joy inf sewing this block, and it set the tone for a creative Block Challenge ahead.

 

Block 1: Four Corners

Four Corners finishes at 10” x 10” and uses easy-to-piece units for a calm, classic start to the challenge. Lori’s design invites you to play with contrast or go for a soft gradient feel, depending on your fabric choices. Whether you’re a confident beginner or a seasoned quilter, this block is a great way to ease into the project with success.

Sew with Me

Here’s how I approached my Thimbeliba version of Four Corners:

  • Fabric Choices: I used prints from Thimbelina for all four corner units and center square, focusing on balance between lighter and deeper tones.
  • Color Flow: I let the natural palette of the collection guide my choices, choosing prints that gave the block a gentle movement.



    A Hand Stitched Detail

For this block, I added a small line of hand stitching before quilting. I used Aurifil embroidery floss and stitched a simple echo about a quarter inch inside the block. Working with three strands in a coordinating color keeps the outline soft and lets the piecing stay the focus. It adds a gentle bit of texture to the finished block, and once the quilting goes over it, the hand stitching shows through in a subtle, handmade way.

Sharing Tips:

  1. Double-check directionality on any directional prints before sewing.
  2. Lay out your block fully before stitching to make sure you love the placement.
  3. Take your time pressing seams, this block looks best with crisp lines.

Quilting Together

One of my favorite parts of the RBD Block Challenge is seeing how many ways one design can come to life. From bold color blocking to soft vintage prints, the same pattern becomes something completely unique in each person’s hands.
