Hugsss, you are in the right place here, surrounded by new friends and cheerleaders on every side!! We all understand, from beginners like me to those who have many years of experience. I still struggle to keep my seams at 1/4" but at least am improving at seeing when they stray right away. To improve your self-esteem, just post a pic of one of your blocks, mistakes and all, and everyone will praise the things you have done right and make you smile and feel so much better. But no quilt police to pick it apart and criticize you, unless you ask for that kind of input.
Ask your questions and there will be answers galore with many options to choose from.
When you don't understand something, there are tutorials and pictures to study, and explanations when asked for.
It's a wonderful place full of wonderful people. Welcome and huggggggggggs, Linda aka wildyard
