If you want something wider or longer or stronger or softer (not as scratchy to the skin) than the standard Disney-type lanyards, I suggest you make your own. I did this about four years ago, and it was <b>very, very</b> easy.
You can buy a variety of mesh (non-elastic) at any fabric and most craft stores. The mesh is sold by the yard, and is usually on big elongated plastic spools in the notions or ribbon area.
Measure the length that you think would be comfortable for you, make sure to account for overlap at the bottom for velcro closure, and then add two inches. This will only cost around $2-$3.
In the same notions section, purchase a package of self-adhesive velcro squares that matches the color and width of the mesh you selected. If you can't find squares, you can use the long pieces of velcro, and just cut it to match. This costs about $1.50.
Also in the notions area -- you will find a variety of hook devices that can be hung from the bottom of the lanyard.
Finally, you want to purchase the strongest <b>fabric glue</b> you can find. Ask a knowledgeable salesperson to help you select, and show them what you plan to do. The glue will cost about $3 -- but it will be a lifetime supply

and great for all kinds of things.
Assembly:
Fold-over one inch at each end of the mesh -- enclose the hanging device in one of the loops -- and use fabric glue to permanently hold the "hem" in place. Place the two glued ends under a stack of books and forget it until tomorrow.
Attach the velcro squares to each end:
Remember to put the correct part of the velcro on the correct side of your lanyard. Try it on to be sure.
You can use fabric glue to make a better, more secure attachment, than just the velcro's standard self-adhesive.
Do not attempt to "unlock" the velcro yet!
Again, stick the ends under a stack of books and forget it until tomorrow.
And that's it!
If you can sew, and have access to a machine -- you can sew everything down instead of using fabric glue.
