I've enjoyed participating in VAL'S archive posts. Visit her and she is much better at sharing her idea for this. AND it is fun to go back thru your old posts to match up the week's theme. I haven't always had something to share, but do love visiting those that do for some wonderful inspiration.
It's all in celebration of her #200 Archive Post and she plans to keep it going. If this is something new to you, go check it out and consider joining in with all of us the next round of 'archives'.
