If you use traditional templates to cut your pieces, you will need to use scant 1/4" seam allowances.
However, if you follow my techniques, you can use either a 1/4" or a scant 1/4", as long as your seam allowances are all the same.
A scant 1/4" makes allowances for the turn of the cloth, so that the finished project is the desired size. A regular 1/4" seam allowance will be slightly smaller when finished.
