Jeanine, thank you for the Brazil specific tips! I have seen that Mundial brand but didn't know anything about it; will definitely look for some good snips here then! Thank you!
I do have one tiny spool of Linhas Corente; it is definitely a nice thread! I only seem to find it in tiny spools though, 100 meter or so, but it is nicer than the other stuff I get, at least as far as hand-piecing goes. The other stuff tangles, fuzzes, etc. The Corente, not at all. I need to make the effort to get to the BIG shopping area for fabric/sewing stuff, which I only just discovered in my city recently. Takes a great deal more effort to get there, but what a treasure trove of stuff!! I could have easily stayed hours, but had only enough time to grab fabric to back my son's quilt and also to back my (eventual) Brazil quilt. *THAT* was a piece of pure serendipity, as I've designed this quilt based off the sidewalk patterns of Brazil, and what did they have but a fabric patterned in the exact sidewalk pattern that makes the outside edge of my quilt!!!!! I bought loads of it, as I haven't planned what size, exactly, the quilt will be. Can't wait to start on that!!! Not until I finish the baby quilt and my son's quilt, though....
Continued thanks to everyone for the great tips. I will definitely look for the Nancy Hargrave book on Kindle; that will be wonderful! and will figure some way to create a slider; was thinking even a large piece of vinyl would work, no? such as you can use for covering seat cushions? That big clear vinyl? Or would that stuff not be slippery enough? Probably something like that, though, I can find here in Brazil -- maybe not the name brand item, but some substitute that will work just as well.
If I can be diligent in not buying fabric I don't need (ahem), I'll have sufficient funds for the tools I *DO* need. As I'm sure you all know, that's easier said than done!
'Tis an expensive hobby my friend started me on......but, man, is it FUN!!!
