OH MY WORD!!! That is sooooo beautiful! Haven't done an indirect method yet, but I think most people use contact paper. Think the contractor's paper - heavy craft paper w/work also. I use it a lot for making patterns. It's quite sturdy, so I think it w/work fine. Wonderful project. You did a beautiful job. Welcome to the forum. Keep us posted on the extension.

Thanks, slow.

Wouldn't using contact paper pull the glass pieces from the thin-set when peeled away?

I thought I needed to use something that would allow water to dissove the glue that held the glass pieces to the base, no?

I think if you wait until it has cures enough the glass won't pull away. I haven't done it though, so I'm not sure. the contract paper should work fine

when they show contact paper in use, its always noted that they don't pull it up but peel it sideways or low. I would go with Slows suggestion of the brown kraft/construction paper so that you can draw right on it. Thats very nice btw, love the design!

I agree with Slow that a brown type paper should be used.
Useing a water soluble glue when you place the finished piece, you simply water sponge the paper, then peel off the paper.If the thinset is set, it won't pull the tiles.

I've only tried the indiredt method with a small project and I used contact paper. I was too impatient and peeled it off too quick and ended up with crooked tile!
I think you've gotten some good advice about kraft paper and water soluble glue....you can learn a lot here... like, the god of wind's name is Astrias. :)
It's a beautiful mosaic, btw.

Welcome to the group... .I have to agree with all about the brown craft paper and weldbond glue...Only I would not do it that way, I would be different and do the whole thing on the fiberglass mesh and then set it into thinset. I really like picking up the whole thing or pieces and setting it down, done...quick is for me.
I have yet to do an indirect where you lay your tiles upside down, but I doubt if I could do it as I don't follow a pattern and my design changes as I go. I never know what I will do next..lol
I love your design and think it is beautiful, if what you do next is half as nice it will be a knockout.

Hey Flag that is usually what I do, just start and let it happen. I get all flusterd when I try to design a pattern then mosaic it.
I'm not sure I would use Weldbond tho, expensive, elmers will work if you are going to sponge it off.

Thanks for all your advice. I'm more of a planner than a design-by-the-seat-of-my-pants kinda gal. I need to have a pattern to work from before starting a project.

I've been reading all the posts and enjoying the pictures of your projects. Wow, lots of talent here.
