There is no pattern, but you can read Julia's description of how she made hers by following this link https://www.instagram.com/p/BFOy8caLa92/?tagged=minidwellswap.
I made my own version just slightly different than Julia.
Julia's banner uses Bonnie and Camille fabric, of which I had some scraps, so I used the same color scheme.
The overall size of the finished houses are tiny, about 3"x 4 1.2" with a roof size of 3 x 1 1/2". The size of the lattice pieces between the house are 1 1/2" x 4 1/2" (this measurement does not include the seam allowance).
To make the chimneys, I used the raw-edge applique method and sewed a small rectangular scrap, about 3/4" wide and sewed it to a 2" square, which I then sewed to the roof, using the stitch and flip technique.
The red pinnacles are scraps of fabric cut into triangles approximately 1" long. I used a piece of thread to drape a line for the pinnacles and test how I wanted it to rise and dip, then lightly drew that line in pencil. I placed the red pinnacles randomly on the line and used my machine to sew a black line across their tops. I sewed across the line twice.
I liked the style of writing that was used, so mimicked the font as best as I could and embroidered the saying in black with 2 strands of black embroidery thread.
Before binding, I pinned a couple of easy folded loops onto the backing so I could hang my banner.
The completed banner measures approximately 10 1/2" x 19".
These would make adorable gifts for friends and family. Mine, I think, will look adorable in the laundry room.
