Right, so clearly I've figured out the equation to successful blogging:
ask for advice + offer free stuff = break your comments record
Thank you for all your comments! They've been very enlightening. I'm surprised at how divided everyone is - I honestly thought that everyone would choose one (my preference, obviously) over the other. I'm still not revealing my preference - I'll leave it for a few more days so I can get more unbiased opinions.
Without counting the people who commented on both solids and stripes, I've got 7 voting solids and 6 voting stripes. However, I opened this up to my family as well, which changes things drastically. Stripes are the popular choice among my family and Shawn's family - we've got 7 for stripes and only 2 for solids. Stripes have taken a strong lead and that's all I'll say about that so I don't inadvertently give away which tie I'm voting for.
