i made two types of these for one type i used clear plastic baubles cut in half and for the others i used plastic cups.

you will also need
images you want to use
glue gun
card
faux snow
ribbon
scissors

to cut the baubles i used a knife but be careful not to crack the bauble, do it gently.
for the plastic cup snow globes i cut the top of the cup off and then cut it into a snow globe shape.
i searched google for some snow scene images and printed them on to white card. then i added glue around the edges of the baubles and added some faux snow inside and stuck them to the card then trimmed around the edge. for the cup snow globe take the pieces and stretch it out slightly so that it can sit with the edges flat to the card. then add glue along the bottom part of the cup and glue them to some card and then cut around the edge. for the bauble ones cut a strip of card and wrap it around the bottom of the bauble to look like the stand of a snow globe and glue it in place, then add glue around the bottom of it and stick it to some more card and then cut it out.

then glue some ribbon on to the back and thats it. 3d snow globe gift tags
