This design is one of my favorite kinds, going from one edge of the piece to the other, and pleasantly geometric for those times that curves won't do.
You only need sort-of straight lines to make it work. Don't stress about straight lines. Mine are wobbly too and it still works. Here is how you do it:
a. Start with a short line up, then take your line off to the side.
b. Then another short line up and off to the other side.
c. Keep going up like this, back and forth. Make the length of the lines variable as you go.
When you get to the other edge of the piece it will look something like this:
Now you make another column the same way, right next to it, making sure you only leave a small space between columns. You can see how the columns fit together below. The more variety you have in the length of your horizontal lines, the less obvious it will be that you quilted this in columns.
I have a little video of this design in action right here.
Of course it doesn't have to go side to side; up and down works fine too.
Doesn't that look like stretchy meandering? So if you like the look of the stretchy meander but don't like how all over it is, you could do it this (easier) way instead.
I hope you get some use out of the Planks design. I know I will! Now I also want to share that I'm in this all-star line up of teachers who will be teaching at QuiltCon in 2016. You know how excited this makes me? Unbelievably excited! Can't wait to be a part of the QuiltCon magic. I hope I'll meet some of you there!
