has anyone tried mapping out the pattern of the larger cosmos holo sheet, I feel like I saw something about it here before, but can’t find the post anymore
Now that I have two cards, from different sets (fossil/gym), with the same pattern I’ve found two others for sale, another from fossil and one from jungle. I also know that the cards are laid out on the sheets so I’m trying to figure out which other cards I’d be able to find with this specific pattern
You can pretty easily map out the holo sheet by looking at the holo pattern on any card with large holo field (e.g. WotC promo energies). If you start to look at different sets, you’ll see that the orientation can switch for different sets. For example, I think the Southern Island reverse holos are “sideways” compared to the holo on some WotC sets, like Neo Genesis (I’d have to verify this, as this is just top of my head knowledge, but you can verify by looking for holo pattern landmarks).
I think the most work that’s been done for trying to map out or understand the cosmos holo sheet and orientation during printing has been carried out by @pinn033 in the double swirl thread. Here’s an example of the stuff he was trying to figure out. If you scroll around that post in that thread (up or down), you may find more information.
If you specify what pattern you’re talking about, I think others can chime in and help too. But no worries if you want to keep it to yourself 
Also, I just realized that you didn’t specify Japanese or English. The Japanese and English holo foil sheets were handled differently during printing, which is why you have those “pokeball” orb patterns on Japanese cards and why double swirls are not seen on Japanese cosmos cards.
Hope this was helpful!
@bbobrob ahh yes those are the posts I was remembering.
I am wondering about the Japanese foil though. I’ve just found that my dark gyarados has the same holo pattern as my matching fossil raichu and gym fearow, just upside down.
I’m going to purchase a matching jungle nidoqueen and dive right into this rabbit hole
I’ve decided to go insane.
I put my fossil raichu in a sleeve and traced the holo pattern and then transferred that to blank card that I cut out.
I dub this Alpha pattern. It’s the first one I noticed that is exactly the same on both my raichu and gym fearow (shown in the matching cosmos holo thread).
I’ve also found a base Poliwrath and jungle nidoqueen with the exact pattern.
My plan is to find more cards with parts of Alpha so I can expand my little map out to eventually join Beta pattern:
This is the pattern I found doubled on my base hitmonchan and jungle vaporeon, defined by the orions belt on the top and orb on the bottom left.
Looks like the holo sheet may be flipped in like you said. If you’re feeling extra curious, you can just buy some beat-up holos and acetone them to map out the holo sheet/pattern.
These two Yanma also provide evidence that the repeating pattern is smaller than I thought, at least horizontally.
I did give this a thought too
Yeah, the repeating pattern is close to a card’s width, as you can get those double-half swirls if you have a swirl on the edge of an art box. The pattern is also smaller than a card’s length (top-down), as you can get quaduple swirl cards like on the promo Entei. Shown here is the top-down repeated Orion’s belt pattern.
So you’d only need to sacrifice one card to capture the whole repeating pattern.
Whaaaat, the WHOLE cosmos pattern is only the size of one card repeated across a sheet? Does everyone already know this, I’m so embarrassed!
I thought it would be larger because the number of cards with matching patterns isn’t that big.
I guess going forward I can try to see if I can make my collection all have matching holo patterns, just for fun.
Here is an Ancient Mew missing the white layer, to give an idea of how the pattern repeats for English cosmos. It’s easiest to see the repeating section around the swirls on the right side.
Adding @qwachansey’s uncut sheet to provide an example of the repeating pattern. It’s a high-def scan provided by Heritage, so feel free to zoom in!
That seems kind of fun But, like you might have pointed out, different sets may orient the holo sheet in different ways. And sometimes, it might be hard to match up the holos between cards within the same set depending on how much of the holo you can actually see. Neat idea regardless!
So does this mean there are only 16 types of Sabrina’s Alakazam cosmos?
I am assuming that the cosmos foil itself is standardized?
Not sure why I never thought of it like that but it makes sense.
Then again, why are TPC/TPCi choosing to use a base holofoil that already has printlines on it in the first place? (Specifically modern cards) Do they think we are blind?
You’re making an assumption that each sheet is identical before the ink is printed on it. More likely the cardstock and holofoil layer are coming off rolls, being stuck together then cut so the offset on each sheet is going to be random.
To me it looks like the repeating pattern is like… 0.8 width of a card, and 0.6 height of a card, a very small square.
Now I want to know how they make the cosmos foil itself and see a full sheet of it without any cards printed on.
