Woohoo!!! Months, I’m ashamed to say, after cutting this all out it’s finally done!!
It’s Robert Kaufman’s Dill Blossom and I cheated and just used some red with white polka dot stuff I had lying around.
I had some wonkiness issues when piecing the lining together with the exterior. I fear I’m not a very precise and exact kind of crafter. But a quick email helped clear up the problem and I’m so happy with the finished bag.
