Cottage and Victorian, Can they live in harmony?

I am wanting to decorate my house with rose patterned dinnerware, and beautiful mahogany wood table, but I also love painted wainscotting, and big soft couches, lace, vintage floral, granny chic, doilies. Can they all work together? I also love embroidered things, and homemade stuff. And seasonal decorations. Can it work together? Can it be super casual but pretty at the same time?

Absolutely! It sounds just gorgeous. Not every Victorian person lived in a mansion. I like traditional furniture myself.
Antique cherry in the living and dining room, more country casual in the kitchen and family rooms. The color scheme
blends my rooms together. (I have blue somewhere in every room; sometimes a little, sometimes a lot.) Go to the library for some books with cottage decorating schemes and/or checkout HGTV.com and Cottage Living magazine.
Good Luck!
