I bought her PIPING HOT BINDING tool, as I could see it would come in handy, both for quilts and clothing. It is a clear plastic unmarked ruler with grooves on the underside near each long edge...the groove on one side is 0.25" from the edge and on the other side it is 0.5"
This means you can cut the strips slightly wider and not worry about keeping the edges perfectly aligned when you fold your strip over the filler cord to sew...because you will use the tool to trim the finished piping to have a flange of the exact width.
The covered filler cord rides in the groove of the tool and the rotary cutter is used to cut along the adjacent edge to trim the flange to, in this case, 0.25".
Once the piping for this project was made, it was time to make the blocks.
The pieces are cut using layered freezer paper templates. There was one A, B, C, and D template for each block. I wanted to make more than one block at a time, so I made duplicates of the templates, allowing me to make 4 clocks at once.
After choosing which fabric would go where, the templates were ironed to my fabrics.
I cut out each shape, leaving a generous 1/2" along the curved edge but cutting the other 3 sides according to the template.
Then I began adding the piping to the curved edge of each piece.I chain-sewed these pieces (not cutting the piping between templates) and used a small wooden skewer to help hold the piping in place as I sewed. Susan had lots of helpful tips for sewing these blocks!
See the masking tape to hold the piece in place for sewing...and the wooden skewer which helps spread the ditch open to sew in it.
