I like the handles from the Bow Tuck Tote. They are cut 5 in. by WOF, fold both sides to the middle then fold in half and sew down the open side, the opposite side and more if you want to. Cut in half lengthwise.
As far along as your tote is, I would place the handles between the bag and lining and then sew. I like your fabric choice a lot :lol:
