As they are close to you and your children, why not also get the children involved in making them a special ruby wedding card or banner. We used to make banners using paper triangles like bunting. Each triangle had a letter and was also decorated with something that showed an aspect of the person e.g. gardening tools, flowers in pots, football team colours and the like. Always very treasured - if the amount of time they were left on display was anything to go by!
Another 'home grown' gift - a big glass jar and fill it with 40 'tokens', each one with a grandparent and child thing to do on it e.g. watch a film together, go for a picnic etc. OR forty fond memories for them to take out and reminisce over.
Have fun.
