Well...let's just say that you have to feed it through a roller that will fold it the other way and then have it glued to a mat + frame.
It could be cheap if you just had it rolled. Look around your area. If I can have it done here by a bunch of places (in the middle of nowhere) you can certainly find places there in sunny CA. Watch the tape, watch the pushpins (keep them to the edges, look at mine and how the framing fits). That is a treasure. Enjoy it!
What a present to yourself! I repeat. I LOVE it! |
