Catherine Bobkoski Workshops 2025

The basic rule is that you can paint with oils on Acryclic grounds but you can’t paint with Acrylics on an Oil ground.

We recommend you varnish all oil paintings. It is important to to wait at least 6 months before varnishing, as it takes at least that long for oil paintings to dry. If you varnish, you will protect your art from the back and the front, ensuring your artwork has the best chance to stand the test of time.

We do not recommend painting directly on unprimed aluminum. Think of your aluminum panels as the stretcher bars on traditional stretched canvas. Its what supports the surface you paint on, not the painting surface itself.

3mm ACM Panels are rigid up to 24 inches but are less rigid at larger sizes making them ideal for smaller art works. 4mm Copper Panels are rigid up to 36 Inches but can be made as large as 48×96 inches. 6mm Honeycomb panels are very rigid at even the largest sizes. In addition they are 60% lighter than a 3mm panel making them ideal for extra large works of art. Gallery panels are made with 3mm panels. Their unique design reinforces the panels in a way that makes them very rigid even at extra large sizes!

3mm panel weighs 2.85grams/square inch (0.1 oz) 4mm panel weighs 4.9 grams/ square inch (0.17 oz) 6mm Honeycomb panel weighs 1.71 grams/square inch (0.06 oz), Gallery panel weighs weighs 3.6 grams/square inch (3.7 oz) Even the copper panels are relatively light. The lightest, 6mm honeycomb panels are by far the lightest panels standing at 19lbs for a huge 4’x8′ panel!

There is a wide range of ways of presenting your artwork. Most commonly artist frame these panels. Though that is the most common presentation we offer a couple other options. Below you will find two hanging systems that we offer, C channel hanging system and the click on hanging system. Both are great for, the 3mm, 4mm and 6mm panels. The gallery panel comes with its own hanging system that you can hang on a wire.

Yes! in fact just send us a picture of what you need and we will see what we can do? We have made everything from arches to giant hand made cutouts.

Yes we have tackled some very unique projects. Contact us and see what is possible!

Yes we typically add at least a week to production with any custom shape.

These panels are very thin and light, making them easy and inexpensive to ship. Keep in mind that shipping one of these panels is the same as shipping ten, so bundling can greatly reduce the per panel shipping cost.

These panels, can fit in the tightest spaces in your studio. Being rigid, light weigh and very thin allows them to be stored in the most out of the way areas of your studio without being worried of ripping you canvas!

Unfortunately the biggest panel we offer at this time is 60 inches by 120 inches. Though it is possible to attach the panels together, there will still be seam. We are working on providing solutions for muralists and other artist that work in larger formats.
