This is not my tip, but a tip from one of my blog readers which I thought should be shared. The Ottobre Katherine top has been very popular and I get a comment on it every time I wear it. One of my lovely blog readers Sandra (aka Dilliander) has been in touch with me and I really wanted to share this great tip for marking the ruffle placement on the sleeves. I traced mine on with carbon paper, but it was not a perfect solution. This is Sandra's method:
The template is simply a manila divider and I used a spiky tracing wheel to mark the stitching lines, including the notch at the top so I could position it accurately. The weight of the board made it easy to chalk the guidelines.
