Per request: I’ve purchased them piecemeal from all over. I’m in the US, and for some reason there’s not a wide variety of lush colors available through US suppliers - so I order many from Etsy or Ebay. Unfortunately that means they’re pricey or have high shipping costs.
See photos below of the chips from the majority of my collection:
Cerulean Tides (USA)
iMaterials (Etsy - China)
Rothko & Frost (UK)
SouthernAcrylic (Ebay - UK)
CraftCloset (Etsy - USA)
TAP Plastics (USA)
Galaxy Plastics (USA)
Houston Acrylics (USA)
My favorite supplier by far is Galaxy Plastics from Virginia USA. I get my pearl and “stone” sheets there. They’re cast, not extruded, and these plastics cut/engrave beautifully. Stunning, vibrant colors whether lit from the front or back. Very good quality stuff - highly recommend.
I love the double-sided (glossy/matte opaque) pastel Perspex. I originally purchased those from ebay (UK) and Slice (AU) because I couldn’t find a supplier in the US. The colors are creamy and rich, the texture on the matte side is like velvet. This stuff cuts/engraves beautifully. It’s the best and most consistent quality of any product I own. I am obsessed with this stuff! US suppliers: makers want a wide variety of pretty supplies! Edit: several of the matte/gloss pastels are available through Cerulean Tides, and a range of lighter matte/gloss pastels are available through Houston Acrylics see comparisons below.
The “ice” frosted colors from MODFYbuild are really gorgeous - photos don’t do them justice. Unfortunately they’re sold out frequently.
iMaterials has a great selection of colors and finishes and they arrive fairly quickly considering they ship from Asia. Note: the “minerals” line (cracked ice) scorches and does not engrave well at all, even when carefully masked. Especially the lighter colors.
Some colors worth noting that I’m hunting for a US supplier for are the “Royals Silk” like from wholesalePOS Ebay UK. They are semi-translucent colors with a fine metallic/shimmer coating.
I only have one sheet of sandwiched celluloid (UK). It’s stunning, but I’m not brave enough to engrave that one at all.
If anyone else has sources for their own acrylics, please feel free to share - link on another post or comment in this thread.
Edit to include Houston Acrylics and Cerulean Tides order plus color comparisons:
I receive my order from Houston Acrylics and Cerulean Tides. They both shipped very quickly. I’m pleased with the materials and the orders. The tortoiseshell is especially beautiful. I also got some thins (in black and white) for backing mosaics and an iridescent coated sheet. All cut and engraved well.
The pastels comparison results:
Unsure of who manufactures Houston’s pastel line (possibly UNIWAI?), but they are quite a bit paler and more muted than the Perspex line. This could be a good thing, depending on your projects of course. Cerulean Tides does carrt several of the Perspex pastel colors and several of the UNIWAI pastels! They call their Perspex line “Bold” pastels. I’ve included side-by-sides of the few colors I purchased, compared to their near-counterparts in the Perspex line. Thank you to everyone who shared their own suppliers. From this post I was able to track down several acrylics I thought weren’t available in the US. I compared a few colors below:
Edited again to give a supplier chart with names. To get an idea of each color/finish, the chips are photographed in ambient light, with a circle in the center taken with a flash. The supplier’s websites probably have better quality images, but this is for quick reference:
