Sure thing. For shatters the main thing is just accept that it'll take a while and plan on doing it one or two pieces at a time, ideally starting with the biggest and working down in size. I've seen videos where someone is fitting a whole shatter together in one go and holding it with rubber bands but this almost never works right in my experience.
A pair of good articulating arm clamps is my starting point for almost everything. I like to put the "main" piece directly under the shard that is being joined. You want the pieces as tight as you can get of course but you don't need a ton of pressure on there. The flour in the medium will draw it together some as it dries. If you get a good bond but it cures with gaps or holes in the join, you can fill in later with lacquer mixed with a fine clay. Tonoko or jinoko are the key words if you don't have it on hand.
Usually there's at least one join where you need to set multiple pieces at the same time. Sometimes I'll use a single string tied across the outermost shard to keep pressure on, usually across the rim of a bowl or cup. More than one string is too much to keep track of for me though. And the lacquer fumes are extremely detrimental to rubber and elastic, they will harden and break with a few hours of exposure so I don't use them at all.
A more traditional move is to bury the main body of the repair in a dish of sand, with the part to be joined exposed. Then arm clamps or whatever to hold the pieces together. Just make sure any joins that touch sand are fully cured. The cleaner you work the less sanding you'll have later. But there will always be some so do what's necessary to get it together then clean afterwards. I've even used masking tape to hold some many-pieced shatters together. It's a mess but it works, provided the piece doesn't have any texture or decorative elements that could be damaged by the sanding.
Good luck! It's the most tricky and frustrating part, and where most of the failures happen. You should probably expect some failures and setbacks, it's just part of it.
