For Jerry G,
Psalm 118:25-26 is used at Jewish weddings. I was unable to find a version of it that didn't include the rest of the wedding song lyrics. A version from Lewis Lewandowski (1821-1894) is available here. Take a look through it. Otherwise, I could make up a melody for it.
Would you like הודו ליהוה כי טוב כי לעולם חסדו? I could recite and sing that one on jodidly.
With regard to the moire wire cross craft I mentioned to you here's a cheap-o foam craft version to use as a model. Just count the number of nails you need for each part of the cross. Get some finishing nails and some nice thread or fish line. Put dots on some wood blocks for the kids to drive the nails in, or have someone set the nails for them ahead of time. Then wind the thread or fish line like in this example. It's not really hard, it just takes a bit of forethought.
