Supplies. I found the belt at goodwill and I had all the other stuff already so this is a very inexpensive project.
Use your seam ripper to take off the buckle and open both ends of your belt.
Cut the ends of your camera strap. Make sure you leave a little bit past the little leathery parts.
Stuff your strap ends into the belt.
Fold over the ends of the fabric so your fabric doesn't fray and sew it closed. Make sure you sew it really well so your camera will be secure. You don't want it to fall off.
It's pretty thick to sew through so use a bigger needle to make it a little easier.
Sew around in a box shape. If you can still see them, follow the spots where you seam ripped the original stitches.
Sew the other side next. Use a thimble if your fingers get sore and change needles if you have extra. They get dull quickly. You could also use your sewing machine if you own one.
Not the neatest stitches ever but they're sturdy. You could embellish it with embroidery or patches or buttons if you want.
Tah-dah!!! It's much prettier & softer than the generic strap my camera came with.
