This 58" x 78" lap quilt features fabric and panel from Hearthside Holiday by Deb Strain for Moda. The fabric was released in 2018 so if you are looking to substitute for the panel, you will need 8" x 9 1/2" blocks.
This pattern is FabSwitch compatible. FabSwitch is my free app which allows you to switch out the fabrics in the original design with current fabrics preloaded in the app or with fabrics that you load yourself. You can then print out a revised picture with an updated fabric requirements list. Check out my demo video on the home page. The app is found online at app.fabswitch.com.
