I've been wanting to use this skyline stamp from My Favorite Things since I got it - particularly the way Michelle did with the reflection - and it worked perfectly to represent the Boston Harbor Skyline.
The top buildings are clear embossed to protect them when you sponge - but the bottom reflected buildings are not embossed. You use a darker color marker on the top row of buildings and a lighter hue of the color on the reflected part (see the marker colors on my supply list below).
Then you sponge the sky with Soft Sky ink, Not Quite Navy ink and then a little black ink as per the tutorial.
You stamp the mirror image of the buildings using a mirror image stamp by Rubber Stampede - I got mine at Michaels - it's just a rectangular stamp of plain red rubber on wood. You stamp your image on that with black ink - stamp it upside down on your card stock - then stamp the image using the original image stamp just above it right side up - this works best with a clear stamp which this building stamp is - as you can see where you are stamping it above the mirror image. - clear as mud??? Michele's tutorial above shows pictures so don't panic!!

I had to make panels 3 and 4 the same size because of the size of my tree stamp and I turned it on it's side. I sponged the River Rock panel with certainly celery and Blue Bayou leaving a clear space in the middle - and then stamped my tree from the Natural Heritage set by
