Buttons can be a little tricky and I know you all wanted me to show off my Paint skills again. Two hole flat buttons (buttons without a shank) are fairly easy to sew but you have to give it some room because there isn't a shank or the space under the button to sew. To make room for a fake shank (no I didn't rhyme that much on purpose) all you need is a toothpick. Take your button and place a toothpick between the two holes. You will want to double your thread by tying both ends in a knot just to save time and add strength. Start to sew from the back of the garment. Sew through the holes 3 or 4 times. Once you have sewn that, remove the toothpick. Now come from the back of the fabric and go through to the front but do not go through the button hole again. With your thread, wrap around the backside of the button 3 or 4 times. This is the make shift shank. This allows you to have room for the fabric to go under the button once you buttoned the garment. Now sew to the back and tie the thread off. Your knots will all be in the back. And ta da now you have sewn a flat button!
