What design are you using? How many Star Points are in your design?
I need to know a little more so I can help. From your measurements I am assuming you are making a 4 patch. Four Star points into a star. By finished do you mean after you sew the 4 Star Points together or after you use the quilt block in a quilt?

One thing I do when I am not sure what I need is to cut paper with my templates and sew them together to see what I get. Math wise 3 1/2 + 3 1/2" = 7" but you will lose 1/2" to seam allowance so you would be left with 6 1/2"
I would have to cut two 3 1/2" squares and sew them together to see if that is right but it should be.
Ok I cut and sewed the 3 1/2" blocks and I got the 6 1/2" block. Is this what you are looking for?

When I downloaded the first of Rhonda's e-Books, I had forgotten and left card stock in my printer. I had printed off several pages before I realized it, but liked the look and feel much better than when using plain printer paper.

When downloading the SPB e-Book, I decided to use card stock again. Now I have two of her e-Books and plan to put them in a 3 Ring Binder. I'm rough on my patterns and use my books a lot if I really like them, so this is great. I printed all 47 pages on card stock pages. This way, I can use the blank pages to attach a clear pocket to hold the templates I make for the block on the opposite page. (No more lost templates next time I decide to make the block again).

I'd love to see pics of your miniatures and other items made with Rhonda's SPB e-Book.

Happy Quilting.

Ok If you don't want to use the method of recycling I showed above here is another way you could cut the fabric for a star point and not have so much left over.

Trim at least 3/4" from the template. Here I am using a 6 1/2" template.

Cut the square in half. If you need two differant colors you can make two differant squares and use one of each.

Next cut a piece for the center. I cut mine the same length as the two pieces on each side of the center. I cut it 5" wide. Here you see the three pieces ready to sew together.

Now sew the left one to the center and cut the angle

Sew the other side on and cut out the Star Point Block.

Here is the 6 1/2" Star Point block and the leftovers. There will always be leftovers as that is the nature of the cut down method but there are ways to use the leftovers. You will not waste any fabric. I never throw anything away until it is nearly threads. There are always ways to use scraps.
This way of cutting however will have less leftovers than the swatch method. I prefer to have the larger leftovers as I reuse them into more blocks. That way I don't have to sort and cut more fabric. It is already there ready to use. Colors have already been chosen and I can just pick it up and go on sewing.

Ok here is one idea for using the leftovers. I used the three pieces leftover and placed them so they can be sewn in a row. I added another one or two to show the repitition. You can cut more in the same shape and keep adding until you get a long enough row for your border.
