For my 16 1/2" center I chose a pattern called Pyramids. Depending on the rotation of this block it can also be a curling ribbon border. This is strictly 1/2 sq. and 1/4 sq triangles. For the 1/2 sq. cut squares 4 7/8" square and cut in half. For your 1/4 sq. triangles, cut a sq. 5 1/4" cut in 4 pieces (X). Sew the 1/4 squares together and then sew them to your 1/2 sq. triangle[ATTACH=CONFIG]454221[/ATTACH][ATTACH=CONFIG]454222[/ATTACH]This last pic note how the corners rotate around the quilt[ATTACH=CONFIG]454223[/ATTACH]The directions and the pic for curling ribbons can be found at
www.quilterscache.com. In the search box type in borders and she has several listed that you may want to use instead of any of these. If you have questions ask, and please be patient, I have never done this before and kind of going by the seat of my pants. Happy New Year everyone!
