My friend, Rob Bergsohn, and I are planning a fee-based workshop on making these leaf castings in September.
Rob runs the Northern Virginia Portrait Photographers group on http://www.meetup.com. He hosts portrait photography workshops outdoors and in the studio as well as 2-4 hour Lightroom and Photoshop classes from his home studio in Falls Church, Virginia. Rob saw my botanical photography exhibit at Green Spring Gardens in spring 2012 and asked if I would host some workshops with him.
We’re planning the workshop for sometime in September and the dates will be slated for weekend days to allow more participants to join. There will be two dates involved—one date to make the leaves (I’m guessing that session will be about 2-3 hours long) and another date for participants to return (after their leaves have cured) to paint and finish their creations.
If you’re in the D.C./Virginia/Maryland area and think you might be interested in signing up, please e-mail me at email@example.com to get on our email list. When we finalize the dates cost and details, we’ll send out a notice to you. We’ll include a link so you can pay via PayPal on Rob’s Meetup group site.
FYI—if you’re interested in learning Lightroom, check out Rob’s workshops. I took his basic Lightroom class a few weeks ago and learned a lot—for just $25 for a couple of hours of instruction. It’s an excellent value! He offers other studio classes on lighting and composition, so check out his meetup group page here: http://www.meetup.com/NOVAPhotography/ It’s a great bunch of photography-minded people and Rob is always adding new classes on a variety of topics relating to photography. You’ll need to sign up for a FREE meetup.com account before enrolling.

My friend Debbi and I have been making these concrete leaf castings for several years now, and my Garden Club members have also tried their hand at it. We have used Portland cement type 1 for our earlier creations, but then started making them with Quikrete instead. Several artists recommend using vinyl patch instead because it’s stronger, lighter in weight and picks up more detail from the leaf texture and veining. It’s also more resistant to flaking and cracking associated with traditional cement mixtures. The next batch I make will be with the vinyl patch product!
This site here has step-by-step instructions (plus a youtube video). The steps are the same no matter which product you’re using.
Click here for Craig Cramer’s blog posting, “The Secret to Great Leaf Casts.” He recommends using Quikrete. Click here for another site with an extensive gallery for inspiration. David, the artist, recommends waiting 30 days before painting your creations. (I’ve never waited that long—don’t know if I would have the patience!) He mixes Quikrete with his concrete mixture, but I’m not sure what the ratio is. At the very least, his photo gallery will endlessly inspire you!
Since most of the leaves we create are smaller, we don’t often do the chicken wire reinforcement. Larger elephant ears do require a bit of reinforcement, though, and we have made some of those (the larger the leaf is, the more likely you’ll need two people to move it when it’s dry!). Most of the ones we have done are made with leaves from hostas, pokeweed, grape leaves, caladium leaves, and smaller elephant ears. Leaves that have nice, deep veins work best. If you want to hang your leaf on a fence or wall, insert a curved piece of clothes hanger or thick wire (formed into a loop) into the back before the leaf is cured.
Artists Little and Lewis suggest using powdered pigments to color your concrete before creating the leaves. Read more about their approach with hosta leaves here. They have created some really beautiful (and large!) ones using Gunnera leaves, which grow well in the Pacific Northwest.
We haven’t tried the “color-in-the-concrete” approach yet. We do ours in the natural color and then paint after curing is done. Our favorite style is to paint the front and back with black acrylic paint, then rub on powdered metallic powdered pigments (the type often used in Sculpey jewelry projects). We used the Pearl Ex powdered pigment series, and we find silver, gold, bronze, blues, greens, and purples work much better than the pastel colors. We only apply the additional coloring and metallic powder to the front. The back remains black only. Check out Pearl Ex pigments on the Jacquard Products website.
I buy my Pearl Ex pigments from Michael’s or A.C. Moore. They sell them in sets of 12 different colors, or you can buy a larger bottle of one color. It doesn’t take much to cover the leaf. We use a soft cloth (and end up using our fingers) to rub in the pigments, which are very concentrated and go a long way. We find it best to paint the leaf with black acrylic craft paint in order for the metallic pigments to be intense in color when they are applied. Use your 40% off coupon at either store and save a bunch!
The metallic pigments are stunning and you can get a variegated look using various colors! If you try this style, you’ll need to seal the front of your leaf with an outdoor spray sealant to keep the pigment from rubbing off. I seal the front of the leaves with Krylon’s Make It Last!® Sealer, which has a satin finish and dries (for handling) within two hours.
Don’t expect the colors to hold up 100% in direct sunlight over a few years, though. The paint will chip a little but you can always paint over it and do it again to freshen it up. They still look good chipped and faded, though…sort of a shabby chic, relic-look! And you can try a new color scheme the next time around. Remember to seal after every repainting. Even if you hang or display yours indoors, you’ll still need to seal the pieces so they can be handled. And they certainly won’t fade as soon if they’re used as indoor art.
If you want a solid colored metallic leaf, you can use inexpensive acrylic craft paint instead of the powdered pigments. First, paint the front and back of the leaf solid black (the leaf is porous so it will soak in the black) and then paint the entire front with your colored metallic acrylic paint. After everything is thoroughly dry, seal the front of the leaf with the Krylon Sealer.
The good news: supplies for this project are CHEAP, CHEAP, CHEAP and the results are incredible! The downside? Those bags of Quickrete, etc. are HEAVY!
Whichever method you decide to try (Portland cement type 1, Quikrete, Quikrete + vinyl patch, vinyl patch only), I’d love to see your results and will share them on this blog!
