I would suggest looking on these threads for help with the gloves.
My suggestion is,
1) Use test fabric and see how big you need the glove to be.
2)Outline your hand in the fabric you plan on using for the baseglove
(the black part)
3) Take the toip of the glove, and sew on the designs and buttons(or circle thingys)
4) Sew on the backl of the glove and you should be good.
NOTE: When making the base glove make sure to cut the fingertips off.
Have fun being Sora! : D
