Here is my first step-by-step tutorial... and I made it an easy one. I made these blocks for my mom and mother-in-law for Christmas and they loved them, so I thought I'd share. They are easy, although time consuming. And if you think they are just too much work... I would love to make them for you.
Start with Modge Podge, scrapbook paper, blocks (I bought mine here) foam brush, and photos printed on a laser printer slightly smaller than the block. (I printed my photos at 1.22 inches for a 1.25" block), a good cutter and letters (I used rub on letters bought at Michaels, but you can use printed letters or stamps- whatever works for you.)
Cut all you scrapbook paper out to fit the squares and cut your pictures out. I really suggest a cutter here, it makes it way easier.
You then use your foam brush to apply a thin layer of Modge Podge to the block and apply the paper and the photos in whatever arrangement you desire. I like to use a plain or simpe paper for the blocks that I want to apply the letters to, it makes them easily readable.
Apply another thin layer of Modge Podge.
It is very important that you let the blocks dry completely between all steps. Wait a few hours or you could end up with a gooey mess. After they are dry, you can apply the rub-on letters to the blocks by... well... rubbing them on with the end of your foam brush.
That's it, basically you are done. However, the ever overachiever, I like to age mine. To do this, use sand paper, some craft paint (I like Folk Art Maple Syrup) and a foam brush.
Lightly sand the corners and edges (I use a 120-180 grit sandpaper) At this point, I am not above child labor...
Now use a tiny teeny amount of the piant and rub it on all the edges and corners.
They make fantastic gifts, Mother's Day, Valentines Day, anniversaries. It would be great to give at a baby shower with personalized photos of the baby's family.
