I think you should keep the size you have. Since you've not done hexies before this would be a good size to begin with......remember, you can fussy cut some at that size and make some cool design features. Btw did you also order the acrylic template for that size papers...if not, when you do,order the one with the 3/8" seam allowance rather than 1/4".....easier to work with.imho.....and don't forget the glue stick rather than basting those papers!
