Do a google search on "DIY plamp" and you'll get a number of ideas. If you're near a Lowes, you can get a couple of KWIKTWISTs. These are about 30" long and can be used like bread wrapper ties for holding things in place, etc. Plus, the Kwicktwists screw together for even longer reach. You can use them alone, or also pick up some small spring clamps at Harbor Freight or elsewhere for a couple of bucks and attach them to the ends of the Kwiktwists with cable ties. For about $10 or so you can make a couple of really functional DIY plamps.
