If you recall, I am making these totes from place mats I found at the $ store and all the emblellishments are from there, too! First I pinned the ribbon in place on a slant for this one. I used a heavy duty needle on the machine as you would use for denim.
Next I stitched the ribbon in place and joined it at the bottom of the bag by overlapping the two ends and folding over for a clean look.
Then I took a piece of fabric to line the bag with and laid it on the mat cutting around the edge in an oblong just slightly wider and longer than the mat. This left room to turn the lining fabric under, then pinned and stitch to the mat before sewing up the sides of the bag. Next I sewed up each side of the bag and went over the stitching twice to re-inforce.
TIP: I use invisible nylon thread for almost all my sewing projects and alterations. It is strong, can be laundered and ironed over but it helps not having to have many, many spools of different colored threads! It also has a little elasticity to it.
I followed all the same procedure for the lavender place mat with matching ribbon and butterflies. I lined the lavender bag with pink fabric.
