Welcome.....I am of Polish ethnicity...both sets of grands came over from Poland.....
You will learn a lot here......altho it's true Quilts are made up of geometric shapes, it's the matching of those seams that's the critical part....so I think, just my opinion here, it wouldn't hurt to first venture into printed patterns....just til you understand the concept.....don't have to buy books, mags, Internet has many sources of free patterns....try a few...where in Poland are you?
