Adding buttons to your page, It's easier to first sew the thread through your buttons and then sticking them onto your page where desired than sewing through the button and the paper.

Check garage sales and thrift stores for bags of buttons, string and other items that will work on scrapbook pages and cards

Look at local craft stores in the sewing section for tubes of misc. buttons. I found a large tube of a variety of sizes and colors.

look on old clothes or holiday out fits to find the right button, usually cheaper to buy the outfit and cut the buttons off then buy a package of buttons depending on the button and the use you need it for. This is a great tip when doing a heritage album if there was a dress or sweater a grandmother always wore. Take a button from the dress to add to her page to make it beautiful and time less.

Tie the button with DMC floss, then attaching them with glue dots.

Use glue dots (or zots) behind the button and you can't see any adhesive.

If you are adding embroidery floss, ribbon, fibers, etc. to buttons eyelets, or other hard to thread items, try this. I use plastic loops for dental floss. Put your fibers through the loop, thread the end through the button hole and pull it through.
