Sorry for your frustation on your first quilt, but all is not lost. Hopefully none of the squares were cut again by your Aunt. Do show pictures. I am by no means an expert but there are many on this board that can offer great advice and have shown beautiful quilts they have made. To me all quilts I make are like putting a jigsaw puzzle together. I love that process. I thoroughly enjoy sewing the block pieces together then arranging them, not particularly fond of cutting them all but that is part of the process.
I agree with others, you might want to put it all aside for now and start a new quilt with instructions, then get back to this one later. There are tons of patterns of any type you want on You Tube, from books at quilt stores or on line and just about anywhere. The 10 minute block might be a choice- find that on You Tube. I also have a very easy and quick block pattern I have used, and if you PM me I will gladly share the directions. Just don't give up, you can do this. After all quilting should be fun and not a chore, so relax and get someone else to give you pointers on what you have. Good luck and welcome to the board.
