Tricksy!

That's what punches can be............I wanted to make a scalloped edged banner but it needed to be quick to do and I wanted the scallops to match at the point!.....not so easy but this is how I did it.

Draw a rectangle 15x20cm, find the mid pint at the bottom and draw lines to the top corners.. this is your basic banner shape.

Use a Stampin'up scallop punch and place the point as shown
punch along the edge...

Tun the banner and place as shown , (keeping the banner the same face up) punch along the edge.....you should have a near perfect rounded point.

Hope you find this usefull.......
