I'm extremely glad now that I spent those couple of days earlier in the week puttering with the jars, it sharpened my tweezer and superglue skills. With the exception of the tub, everything in this bathroom is wall mounted, and plastic, so it all had to be superglued in place.
The things I've learned about supergluing miniatures:
Don't try to apply glue from the tube directly to the miniature. I use a scrap piece of plastic packaging as a palette, put a dab of glue on my palette, then use a toothpick or pin to spread it in a thin layer on the miniature, only in the places it needs to make contact.
A little superglue goes a long way. If glue is oozing out around the edges or not setting in the time it should you're using too much. It will be messy and the bond won't be as strong.
When I glued the towel holders and switches on the walls I used painters tape to hold strips of skinny stick to the wall, utilizing a square to position them straight and level. I measured and marked with pencil, on the skinny strip, where I wanted to place the switches, then used the top edge of the skinny stick as a guide to glue the switches on the wall in position and level.
Test place your piece a few times before you put glue on it. Make sure you can position it and hold it in place in a single smooth motion without fumbling. Some things I glued on with just my hands, some with tweezers, depending on how small the piece was, whether I needed to apply pressure all over or at both ends, etc. Once you have glue on the piece it's best to not let go until the glue is set.
Don't get impatient. Hold the piece firmly and steadily in place while the glue sets. Apply enough consistent and even pressure to push all the contact points together and hold them firmly but not so much pressure as to bend or break the piece. Don't wiggle. Don't let up the pressure too early. Sing a song, or count in your head. Don't answer the phone if it rings.
Relax. If your arm are sore or your hands tired and shaky you need to take a long break. Be zen with the superglue.
Don't try to superglue material you're not supposed to. If you're not sure if superglue is the right adhesive to use with glass, for instance (it's not), google it first.
Just because the glue has set and is holding your piece in place doesn't mean it's cured all the way. Leave it alone to dry overnight before you start hanging towels on the rods, etc. Don't monkey with it!
Try different brands. I call all cyanoacrylate adhesive superglue, just like I call all facial tissue Kleenex, but I don't like the Superglue brand and don't use it. I favor the Gorilla Glue brand, it's not runny and doesn't set up on my palette instantly, plus there aren't noxious fumes. I've heard good things about the Loctite brand, but haven't tried it. Stay away from generic or dollar store superglue...you get what you pay for. I buy mine at the hardware store, not at the craft store.
That's my two cents....if you have anything to add I always welcome helpful hints.
