Straps like these have been popular with cross-country riders for years. These are more secure than bungees, they're always the right length, and they won't scratch up your paint.

I bought two Coghlan's Utility Straps, 10 ft. long pn 7610. $2.30 ea at K-Mart, etc. I got them at the local independent grocery store, which has a decent camping section. I also used four sliders, about 25 cents each at a sporting goods store, or many fabric stores.
I cut the 10' straps 20" from the end with the no-slip buckle. Don't forget to burn the cut ends - I used my gas stove, as usual. I then used sliders to make a loop in each 20" piece. Each loop includes a half twist.
Then I made loops in the remaining pieces, which are just over 7' long. All the loops have a half twist, and all the loops are about 7" long. I like to pull the loose end out of the slider so that there's about 2" of webbing sticking out, then I turn that back over the slider and put it over the front edge and through the back edge. There are now two layers of webbing going through the front edge of the slider, and three layers going through the back edge. When assembled like this, the slider is almost completely immobile. See detail above.
To use them, you hook a buckle somewhere, hook a strap somewhere else, loop over, around, through, then wind up at the no-slip buckle. Total cost for two straps: $6. Or, you can get equivalent straps from Helen2Wheels, two for $20.
Alternatively, you can buy flat or tube webbing at a good sporting goods or fabric store, and also buy some D-rings and a couple extra sliders. Mike prefers tubular webbing for its extra strength and non-slip features; I prefer flat webbing 'cause it packs smaller and it's easier to handle.

Required: 20' of 1/8" bungee cord, available at a good sporting goods store, about $6.
16 hooks. I bought 8 small 10" bungee cords and cut the hooks off. About $5 at K-Mart.
Tie a loose knot in one end of the bungee cord. Run the cord through one hook's strain relief, then diagonally to the next
hook. At each hook, fold the cord, push the fold through the hook's strain relief, and loop it over the hook. Next, vertically
to the next hook, then diagonal, then vertical. Run the cord through the last hook, this is the same hook as you started with.
Adjust the cord until it is taught everywhere, then tie the two ends together and cut off the excess cord. Repeat three more
times for four luggage straps. About ten minutes work.
Or, buy them from UK Honda. $44. Per side.
Required: eight 10" bungee cords, Four nylon O-rings, Four nylon hooks with sleeve. About $10 total at a camping store.
Take one bungee cord, pass it through the O-ring, center the O-ring on the bungee and tie a simple knot. Repeat with three
more bungee cords. Take one bungee cord, fold it in half. Feed the looped end of the bungee cord through the sleeve of the hook;
insert the loop firmly into the female end of the hook; with a pair of pliers, compress the plastic sleeve onto the hook to lock
it in place. Repeat with the other three bungee cords. Photos and idea by Tim Yip.
