How about finding a seldom used side table, or similar, and then laying them up on top. You could have a piece of glass cut to order, with smoothed edges, and lay it on top. You won't have taken up any more room in the apartment, but you'd display the tickets safely under glass?

Hey!
I'd like to share another idea:
You could hang up a string between two nails or pins quite close to a wall (or through your room since you mention that your walls are full) and hang up the tickets there using clothespins.
I have done this often and it works very well and looks quite good :)
Have fun!

* display them on a glass-topped tray. The glass would protect the stubs, but still allow you to display them

* put them in a large apothecary-style jar - on display, but not individually visible

nice photo album, then leave the photo album out on a coffee table.

Shadow box?
Glass topped tray with the stubs under the glass?
Photo album?
Turn them into a collage?

There are a ton of choices.

If you do consider decoupage, try doing it on hockey sticks

This may seem like a simple idea - but it has a big effect. A shadow box. My husband was a sports journalist not to mention an Ohio State Alumnus so we had a ton of tickets and Media passes to do something with. I bought a black framed shadow box from Target (like this one: http://www.target.com/Shadowbox-Frame-Black-12x12/dp/B001AJDGUQ/sr=1-3/qid=1245156053/ref=sr_1_3/192-1410258-6195528?ie=UTF8&frombrowse=0&index=target&rh=k%3Ashadowbox&page=1) for around $20 I think. It came with pins so all I had to do was arrange everything and tack it down. He loves it and it displays very well, plus, it isn't a permanent thing. If you want to take the tickets out you can without damaging them.

Laminate them, and turn them into bunting.

I'll just resonate a few other comments, but with some twists. Shadow box, but drop them in like a ballot box. Cut slit on top to keep adding to the "stash." The photo album is the start of a good idea, but consider the ticket more. It is not some sort of pristine artifact (photo albums are cliche and kitsch). Treat it like a found object and start gluing them into a notebook and not just any notebook, something that you would enjoy seeing placed on the coffee table. Use PVA the glue them in. I also like the clothes line idea, but maybe use a small steel cable and binder or metal clips.

a few years ago, our frameshop had a customer request a custom "opera ticket" box which turned out beautifully. We used two long skinny hardwood shadow box frames attached back to back, then we routed out an oblong hole at the top of the frame to slip in used ticket stubs. the glass on both sides displayed the tickets beautifully and you get a fun sense of time passing as you fill it. final dimensions of the box were about 24" tall by 12" wide, and about 6" deep.

Love all these ideas, esp. the clothes line one! I've been having a similar problem with concert tickets because I want to be able to see each individual ticket, but without taking up too much space.

what about hanging them from a Photo Mobile?

I like the idea of putting them in a large glass jar, however just note that if you do display them and they are exposed to even a little bit of light over a long period of time, they will fade.

Choose your favorite family photos, especially if you have any of you with friends or family at these games in particular, and use the ticket stubs to cover the mat that frames the photo. You can piece it together, like a jigsaw puzzle, without cutting your stubs (it'll just take a little time to calculate). One thing I'd ensure would be that you have at least a 1/8" white, or continuously colored reveal, between the actual picture and the ticket stub (to give a visual break and set both apart within the frame). Using archival quality tape shouldn't harm your ticket stubs and I believe, though I'm not certain so verify this if you use this method, the tape is reversible meaning it can be removed without harming what it touched.

This takes up a lot of wall space, but thought I'd share anyway! My husband gave this to me for Christmas and now it's become a sort of tradition to do with special concerts/sporting events/etc... It's a framed limited edition print of the Foo Fighters show we saw in Vegas, matted with our room key and ticket stub.

Eventually when we have a house, we plan on having a large collection of these in our finished basement/gameroom! One can dream anyway...

Perhaps you could do what Erica of Urban Grace did with her matchbooks? She has them framed just beautifully.

Look in second hand furniture stores for glass top display tables. Ones where you actually have a visible lower storage/display area, rather than just a table with a sheet of glass on top. That way, you will be able to layer tickets without worrying about creating an uneven table surface below the glass. You also won't have to worry about the weight of the glass bending your tickets (however slightly) when they are layered on top of each other.

It's a bit pricey for me, but I'm pretty sure I remember the Ikea Liatorp coffee table being like that: http://www.ikea.com/us/en/catalog/products/50087072

I gave each of my sons a spherical clear glass vase for their stubs. It looks clean, doesn't take up too much space, and they can see and add to the collection easily. You could also use a jar, fishbowl, or any other glass container that works with your style.

Flood the floor of your apartment and install freezer units. Lay the tickets on top of the ice and then add another layer of water to freeze over them.

Not that big of a fan? Okay, I totally like the glass vases. For those extra special tickets, I'd suggest cutting lines across the top of hockey pucks and those fake plastic ice cubes into which you can insert the tickets so they stand. A little vignette of a modern glass vase and a few hockey pucks with tickets standing in them. Yeah, that's the ticket...

Have fun!

@fledgling, those are hilarious ideas!

I think that the glass container sounds really nice and decorative. However, if the exposure to light is an issue, then why not store them in a scrapbook-ish situation that you can either display or put away to protect from light. I was thinking one of these accordion type ones that martha sells at Michael's (http://www.michaels.com/art/online/displayProductPage?productNum=pc0987) You could even add some clear plastic pages in there to hold little books containing more of your tickets. See the example here from the Craft's dept (http://thecraftsdept.marthastewart.com/photo-galleries?album=1&gallery=88)

Hmmmmm maybe you could...

1. Arrange your tickets and color copy them onto paper. Then you could use the new printed paper for wrapping gifts, lining drawers, stationary, etc.?

2. Similar to above, but have your tickets screenprinted onto an item of clothing or bag or whatever. Be the envy of all your friends when you show up to a game with your hip new DIY shirt.

This way you could still keep your tickets tucked away in a box, but you would have some nice ways of showing them off and sharing them with other hockey fans.

I remembered seeing this craft so I looked it up again. If you put them in coasters, you can display them under your beverages when you are watching the games on TV. Unfortunately I wasn't able to find the actual tutorial but the photo is inspirational and you can probably look up some techniques (decoupage? lamination?) for how to get this effect: http://recycledcrafts.craftgossip.com/concert-ticket-coasters/2008/12/21/

I mount mine on adhesive-backed magnetic sheets and use them as fridge magnets. They look neat, since they're all about the same size and color and have that nice, regular shape.

Cyra, If you find a solution you like can you please post a photo of it? I'm in the exact same situation (except with Blackhawk tickets). The problem I've run into is that the tickets aren't very colorful. Anyone know a way to display them that doesn't look so bland?
