Am working on a Spinning Spools Pattern, called Teepee Sunrise. It came with almost all of the templates pre-printed on template plastic. However the largest piece was not. it is a large triangle that is 6" x 12" and then they state add seam allowances. now I know this is splitting hairs but do you measure the 6 x 12 then add the 1/2 inch (quarter for both sides) or do you measure 6-1/2 x 12-1/2 to begin with. Believe it or not you get two different angles.....this is a link to a current listing for the pattern....

Thanks

Personally, I would email the person you purchased this pattern from and ask them as each designer has their way of how things are done.

Thanks for the link

Add the 1/4 inch to each side (all 3) of the 6 x 12 triangle.

draw the triangle on graft paper and then add your seam allowances. When making templates I suggest always drawing them to the finished size and then add your allowances. I draw on the graft paper and then glue to plastic and then cut out. I will then punch a small hole at the corners to make sure I mark where they should match up. This is important for any shape which is not a square or rectangle.

I agree with Holice, I always draw out the pattern and then add the seam allowance. :D:D:D

This is probably the VERY BEST advise I have ever received here on the Board. Punching a hole in those corners is brillant !!!

Very helpful link, thanks!

Cute pattern!

The pattern looks as though you will construct the TeePee first, then add those larger triangles. I wouldn't do a template. Rather cut a rectangle fabric piece, then diagonally cut and those are the two pieces for the background.

The other hint ... I'd cut the rectangle larger, perhaps at 7x13, slice diagonally, then sew in place. That way you will have extra fabric, and then can easily square each block up to perfect straight edges and square corners.
