For odd shaped gifts:
Set the Odd thing aside....Concentrate on the paper, which you will need lots of. Now make a big envelope of the paper. Then put the odd thing inside it...I saw this on television, a lady who had won a gift wrapping competition demonstrated the technique.
Also, footballs, or other oval or round shaps can be wrapped to look like a big xmas candy.
Just twist the ends, and tie with long ribbon!
