Here are the fibers I used for the background.
The top one is the heavy thread I used for the trees. Next is a loose spun thread used on the darker meadow areas. Finally, the lighter meadow areas were stitched using a silk with flames, which means tighter areas and looser areas. Laid down with long stitches, these fibers show off their irregularities to make a rich background that looks complicated while actually being fast and easy to stitch!
Prayer: Father, thank You that our irregularities make us unique, beautiful, fitted for individual purposes in Your world.
