Silicone Molds for Floral Preservation, Resin Crafts & Woodworking: The Complete Guide

Whatever you're casting, the mold decides how the finished piece looks. Shape, depth, wall strength and surface finish all show up in the final result. That last one matters more than most people expect. A mold with a glossy, shiny interior gives you a piece that comes out smooth and shiny on every side, so in most cases there's no sanding, no polishing and no touch-ups after demolding. You pull it out and it's finished.

We're a family-owned, mother-and-son shop in Illinois, and every mold we sell is handmade in the USA, many from platinum-cure silicone. With over 75,000 molds sold and over 10,000 five-star reviews, we've seen what works for resin artists, woodworkers and floral preservationists. This guide walks through how to pick silicone molds for each kind of project, and how to take care of them once you have them.

Floral Preservation Molds

Floral preservation is where mold choice matters most. You're setting something people care about, like a wedding bouquet, a memorial arrangement or flowers from a milestone moment, inside a block of resin. You only get one shot at it, so the mold has to be right.

Wedding Bouquets and Memorial Flowers

Wedding bouquets are bulky. Roses, peonies and full stems take up real space, and cramming them into a shallow mold flattens the arrangement you worked to save. Memorial flowers are often the same story: a few precious stems or a full arrangement from a service, and you want them to look natural and unsquashed. Our deep square and rectangle molds come in 1", 2" and 3" depths, and for most bouquet work the 3" depth is the one to reach for.

Why 3-Inch Depth Matters

Depth is what lets flowers sit in the resin the way they grew, with room for petals to keep their shape and for layered pours. These deep pour molds give you space to build an arrangement with real dimension instead of pressing everything flat. If you're working with full blooms, start with 3".

Why a Glossy Interior Matters

Preserved flowers are delicate, and so is the surface of a finished block. The shiny interior of our molds transfers a smooth, glossy finish to every side of the cast piece. Pieces release cleanly with no damage, and in most cases there's nothing to sand or polish afterward. Our large floral molds also have wall stiffeners embedded in the silicone, so the walls don't bow when you pour.

Popular Shapes

Blocks and rectangles are the classic choice for bouquets. Frames let you display a photo alongside the flowers, and our 5x7 picture frame mold holds a 5" x 7" photo surrounded by preserved flowers. Hexagons are a favorite for a more modern look. For memorial pieces, our deep molds include crosses, rainbows, hearts and angels.

Resin Craft Molds

Resin molds are where a lot of people start, and for good reason. A small mold, a little resin and an afternoon can give you something you're proud to hand to someone.

Coasters, Trays, Letters and Small Gifts

Coasters are the everyday favorite, and our coaster molds come in a range of shapes so you can build a matching set. If you want something bigger to show off a pour, take a look at our tray molds. Letters and small gift pieces are great for personalized presents, and the same glossy interior means they come out shiny and ready to give.

A Tip for Beginners

Start with a simple shape and a single color. Get comfortable with mixing, pouring and timing before you try layers, swirls or embeds. If you want to see what other makers reach for first, our top-selling silicone resin products are a good place to browse.

Woodworking & Epoxy Molds

Woodworkers use silicone molds to combine wood and epoxy into pieces that are hard to make any other way. The mold holds the epoxy in place while it cures, and the glossy interior leaves a smooth finish on the cast surface.

Charcuterie Boards

A board with an epoxy section or an epoxy border is a popular project, and our charcuterie board silicone molds are built for exactly that.

River-Style Pieces and Turning Blanks

River-style tables and boards use epoxy to fill the gap between two pieces of wood. Turning blanks combine wood and resin so you can take them to the lathe. Our full range of silicone molds for woodworkers covers these projects and more.

How to Choose the Right Mold

Start with Depth

• 1" depth: thin pieces like coasters and slim keepsakes.
• 1.25" depth: a little more room for embeds and slightly thicker pours.
• 2" depth: small flowers, layered pieces and chunkier projects.
• 3" depth: full blooms, wedding bouquets and statement keepsakes.

Then Choose Size

Once you know the depth, pick the footprint. Lay your flowers or your materials out on the table and measure them. Leave a little breathing room around the edges so nothing is touching the walls.

Mold Care and Release

Mold release is not required for demolding. A silicone-safe release spray is optional, and it can help extend the life of a mold, which is why some of our product pages recommend one. Rinse your mold with mild soap and water after use, let it dry fully and store it flat so it keeps its shape.

FAQ

Yes, silicone molds work for both resin crafts and epoxy woodworking. Just pick the shape and depth that fit the project you have in mind.

How do I keep my molds in good shape?
