Welcome to the 2026 Block of the Month, Butterfly Sanctuary. This year-long project brings together vibrant threadwork and mindful stitching in one stunning quilt. You can stitch it in Foundation Paper Piecing (FPP), Hand Embroidery Wool Appliqué, or both. Choose the technique that fits your style, or try them together.
At its heart, Butterfly Sanctuary celebrates growth and transformation, with each block introducing new stitching skills that build upon one another, unfolding into a larger story as your quilt comes to life.
Best of all, the patterns are completely free. Simply sign up for the WonderFil newsletter and each month’s pattern goes straight to your inbox. Plus, we have a Block of the Month Facebook group where you can share your progress, ask questions, and connect with fellow quilters along the way.
Wool Appliqué Quilt
The Butterfly Sanctuary wool appliqué version is a wonderful way to explore our Merino Wool fabric while building your skills in appliqué and hand embroidery. To get you started, we put together thoughtfully curated thread packs that include everything you need to create rich textures and beautifully embellished details.
First, the wool appliqué thread kit includes Ellana™, our 12wt wool thread designed for stitching and embellishing appliqué edges. It pairs beautifully with the WonderFil Merino Wool, blending into each piece for a clean, professional finish.
Also included are two packs of Eleganza™, our 8wt Egyptian cotton thread in a limited-edition Butterfly Sanctuary tin. Because it comes in both solid and variegated colors, this hand embroidery thread works beautifully for all decorative stitches and embellishing details.
Want to start the BOM quilt but don’t have the time to cut out your wool appliqué shapes? We’ve got you covered. Our pre-cut appliqué kits come ready to stitch, so you dive right in without the prep work! Simply sign up for our pre-cut wool block kit and receive all your appliqué pieces each month, delivered straight to your doorstep.

We also have a video stitch along for the first block, so you can follow along as you get started.

Foundation Paper Piecing Quilt
The FPP version of the Butterfly Sanctuary quilt features the same 12 butterflies, each beautifully spread across the individual blocks.
To help you achieve clean, precise results, Butterfly Sanctuary also offers a Foundation Paper PIecing thread pack. This set includes three colors of DecoBob™, our 80wt lightweight, cottonized polyester thread. Designed for strength without adding bulk, DecoBob™ is your go-to thread for achieving flatter seams and crisp edges.

The patterns are free all you need to do is sign up for the WonderFil newsletter and each month’s block will land straight in your inbox.
Be sure to also check out our Butterfly Sanctuary FPP starting guide for a walkthrough on how to read your FPP patterns to begin your quilt!
BOM piecing pack:

This incredible 80wt 2-ply cottonized polyester thread carries a textured matte finish and has been specially treated to behave like cotton while eliminating stretch. Fine yet durable, this lightweight thread reduces bulk in stitching, resulting in smoother, rounder curves, and is ideal for achieving acute miters for a clean, professional finish.
