Okay so humor me as this is my first tutorial and it's kind of rudimentry. (sp)
normal sewing supplies: machine, thread, scissors, seam ripper
Two flat sheets the size of the comforter you wish to cover
buttons (I used 10)
take a look at your sheets. See on the top edge where the printed side is folded over onto the back side of the sheet? Rip that seam out. Repaet with second sheet.
Decide which sheet will be the top and which will be the bottom. Take the bottom sheet and cut off the little folded over flap at the top.
This picture looks wrong, the top stip looks like it has a crease in it. it shouldn't.
Step 3: Pin and sew the second sheets flap to the top edge of the first sheet. (the part you just ripped)
Hem up the sides of the flap to make it neat and heam along the long edge.
Step 4: The part I hate. Sew four button holes along the top edge of the main sheet. try to evenly space them. and make sure they are bigger than your buttons. You can always handstitch them to get a tighter fit later. This is particualry inportant if you are using different kinds of buttons.
Step 5: Fold down the flap made from the second sheet and sew up the side so it makes a little pocket.
Step 6: Sew the rest of the button holes in. It should have four button holes on each side
lovely picture of a button hole.
Step 7: Pin the Back sheet to the front sheet, right sides facing. sew up the three sides.
Step 8: Turn your duvet cover rightside out and stuff the duvet in it. Be sure it is in there evenly and isn't twisted anywhere. Mark all your button holes with safety pins. I pin it directly to the duvet and catch the edges of the cover so it all stays in place. Sew your buttons onto the DUVET, not the cover. Move from hole to hole sewing in a button and adjusting the button hole for a tight fit.
You can either stop here and your duvet will work fine or if you choose to you can add some snaps to the back flap so it stays closed better.
If you have any problems understanding this or need further instructions let me know and I'll try to help.
