Think of a little house shape. take a piece of plain computer paper. fold the paper in half the long way to get a long center guideline. Draw half a house on it, turn it over and trace the other half. Now cut out the house out, and also cut along the fold lines. You will have 3 pieces. Take the house piece and draw a roof line in an upside down V, about a half inch wide. Cut that out too, and cut it in two pieces along the fold line. Now you have 5 pieces.
Take the body of the house and pin it to some interesting fabric. Both Right side out. Take an pencil or pen and draw around the shape of the house on the fabric. then draw a seam allowance around that, at least 1/4" or a bit more wide. Cut out the house on the outside of the seam lines.
Then do the same thing to each of the halves of the roof pieces.
You will have 3 cut out pieces. Using a straight stitch, and right sides together, sew one of the roof pieces to the
edge of the house, open it and finger press with a little
piece of wood. Then sew the other half of the roof on the same way.
Now you still have 2 halves of the space outside the house. You can cut those across just at the bottom line of the house.
Take each of the upper halves and lay them right side up on some blue fabric, draw around them twice to get the seam allowance, cut them out. and with wrong sides together, sew them onto the house, bendihg them to fit.
They will flatten out.
Now if you want, you can tape the two bottom pattern pieces back together and trace and cut them out and sew them onto the bottom of the sky and house, to finish the block.
It is the "how to" you are learning. You will discover it is not necessary to draw the line around the edge of the pattern, just the one around the seam allowance. Every piece has to have a seam allowance.
It is not paper piecing. It is fabric piecing.Remember join them by right sides together, unless it is an applique
About the details...Like a door and windows.
There are two ways to do this, you can cut and sew, piecing them or you can applique them on top.
In some cases you can simply straight stitch a rectangle with the seams folded under - the lines of stitches being the lines of detail on the fabric image you are making.
For the tree, The straight or curved topstitched lines along the edges will blend in with the rest of the stitching to deliniate its bark.
This is just a practice to show you how plain piecing technique is used to produce a landscape quilt top.
If you can possibly find it - buy a copy of Ruth Mc Dowell
Landscape or flowers books. She uses this technique. and also is a very nice lady, and we were acquainted when I lived in Woburn.
