DIY Valentine’s Day Vases

Since Valentine's Day is quickly approaching, I decided to turn my winter vase into a collection of Valentine's Day Vases.

I took 4 of these vases from Dollar Tree and applied fabric glue with a paint brush.  Then I wrapped some brown yarn around them until they were covered.

I used various white or off-white items from around the house to spell out the word “LOVE” – a piece of lace, a felt rosette (here's a tutorial), buttons, and a piece of white yarn.

And there you have it.

And now, my dear readers.  Here's a question I have for you.

I have no idea what I'm doing when it comes to filling vases.  And, to further add to my problem, my decorating budget is $0.  I have to use what I have around the house.  And in this case, these are the only flowers I had that were white or pink, or any sort of Valentine-y colors.  So, do you have any ideas for how to fill the vases using only these flowers or things I could find outside?  I'm no good at this.  Help!
