[Plugin: Woocommerce] Custom Variation

Hello,

My site is http://www.thepaisleybox.com and I use woocommerce.

I have a product that requires a variation option that the customer would need to fill out. In other words, I would like to create a variation without a drop down list.

This is an example of the type of product (http://thepaisleybox.com/product/personalized-jewelry-box-turquoise/ ). For initials, I just create 3 drop downs where the customer selects the 3 letters. However, I need the customer to be able to submit a full name so 8-10 drop down selections will be too much.

Is there a way for the customer to fill-out what they would like rather than choose from a list of pre-determined options?
