Review on Arteza Set Of 50 Blue Felt Sheets - 8.3X11.8 Inches, 10 Craft Felt Tones, 20 Soft & 30 Stiff Non-Woven Felt Fabric Squares, 1.5Mm & 1.3Mm Thick Sewing Fabric For DIY Projects by Reginald Holman

Really bad consistency as far as thickness and smoothness goes, I wouldn't have guessed these are from the same brand at all. Most sheets are very thin and feel more dense, with some that are noticeably thicker and a bit softer, and some kind of in the middle. The thickest sheet is about 2mm while the thinnest is barely 1mm (though the thin ones still feel dense, definitely not flimsy). Some are also smooth and some are rough. One of the gray colors is more like a marbled/heather gray instead of solid gray.Also note that the fluorescent, glitter, and metallic sheets are NOT STIFF. They're regular floppy felt (though the metallics are slightly stiffer by virtue of being coated on the one side).I've included a picture showing off the differences in thickness, in case it helps anyone decide. From the top down the stack is: metallic, fluorescent, glitter, and then the rest of the colors sorted by thin, middlish, and thick.I'll keep these to use, but I doubt I'll buy from this brand again, and I wouldn't recommend them to others unless they're fine with the weird inconsistencies.
