So this is my FAVORITE method for adding borders!
First I cut my border strips the length of the fabric parallel to the selvage. I then lay the two border pieces on top of the background they will be attached to, right across the middle.
I then use my ruler and rotary cutter to trim the borders exactly the size of the background fabric.
I then pin the borders to the background and sew! Note the ruler was ONLY used for cutting a straight edge - NO MATH WAS USED!!!
Press the borders open and repeat the process for the remaining borders.
All that is left to do is center the tree shape in the center of the blue block and baste in place. By the way, this is the only basting required.
Until next time,
