I apologize for the delay in this post. Here are my DIY save the dates...TA-DA!
After my huge black pen fiasco I regained my self-confidence and decided to try again at handwriting all the addresses. I got a couple of white gel pens from Michael's which I think look a million times better.
I didn't have it in me to hand write all the return addresses so we just printed them on transparent labels and stuck them on the back. We also used a little piece of fancy fabric tape as a finishing touch.We were originally going to use seals but they ended up being a little big for the envelopes. Hopefully I'll be able to use the seals on the invitations.
Then I put them all in gallon ziplock bags to protect them from the elements until they were safely in the hands of the USPS.
