This block came from a Block of the Month quilt on HGTV.

I modified the block.  The roof is felt - and yes, the shingles are 3D -- each row cut to look like shingles on a roof.

Seed Beads were sewn down, individually, in the sky, to look like falling snow.

See below for
close-up.

Snow on chimney
Backstitched a row of Seed Beads around the perimeter of the appliquéd snow on the chimney.
