I have made a Grandmother's Fan quilt and I would like to add a straight border to it. Is there anything I can do to make sure it come out nice and flat with no waves? Also I would like to scallop the outside edge. Any help there?

No help on the scallops but attaching a straight of grain border to a bias edge isn't too hard. I would have stay stitched the edge of the bias before attaching the border. It helps keep the edge from stretching. Than I would sew on the border with the bias edge on the bottom.

I measure the bias side and then cut my boarder. I mark centers and pin alot, then sew. That way I don't stretch the bias edge.

I agree to stay stitch that edge you are going to join to the border. Use a smaller stich 2.5 or 2.0 . Starch the edges before stay stitching.
But it could be very problematic if you use cross cut fabric rather then lenghtwise grain for your border. Lenght wise does not stretch .. but cross cut ( across the width of fabric) will ... so combining a cross cut and a bias could give a really off kilter result.... in other words you could have the whole outer perimeter stretched bigger than the rest if the quilt.

Perhaps hand basting might help here.:)

I'd also use a lot of spray starch to keep the bias edge from being accidentally stretched.

This is where I get out the bottle of Elmers school glue. If I glue along the very edge of the borders instead of pinning, it helps to stabilize the edges too :D:D:D

Since seeing the glue thing I have stocked up while the back to school specials are in full swing. The Elmer's washable is now .40 per bottle at Walmart and it is like a new best friend to me in tight or difficult sewing situations.

As previously mentioned, spray starch and stay stitching would help. Here's a tutorial Eddie did for scallops. Note: the pics start on page 3.

i would stay stitch the sides of the bias edge before putting on the border.
