100th ETSY Sale Give-Away

I've decided I'm going to give something away for my 100th sale on ETSY. I've wanted to do give-aways all along, but time just hasn't permitted yet. But, I think the 100th sale is cause to celebrate. But what should it be? A monster tote? A personalized apron? I'm making up a full apron that has the same face-portrait like the portrait tote...that might be fun. Or I could just make something that isn't personalized so it would be ready to ship right away. Or maybe I should do something totally new. Hmmm...help me decide. You guys let me know what I should give away. You can comment here or convo me on ETSY. I also haven't decided how to give it away. First person to contact me after the giveaway starts...or the 100th...or the first person to answer a question...hmmm...so many decisions!
