Well I found out the hard way that my 1/4 inch foot that I purchased for my Brother machine is not a true 1/4 inch. I sewed three 2 1/2 strips together and then cut them into 2 1/2 blocks. After sewing them together and pressing it was supposed to measure 6 1/2 inches. I had a piece that was supposed to get sewn onto this that measured 6 1/2. Well guess what, it didnt fit. Not even close. I took out all the stitches and did it without the 1/4 inch foot and guess what.... it fit. You would think that when you buy a 1/4 inch foot it would work.
