I love your patterns, but I have to agree with Ellie. They are more challenging than I would recommend for a new Quilter. If you have experience in other types of sewing that may make them less of a challenge, but you have to be the judge of that. Making samples out of scraps first is an excellent idea. That should let you know if you want to attempt the whole quilt.
I Love your fabrics. As a matter of fact, we've used two of them for a quilt for our niece:
Molly's HS graduation quilt
If you do the quilts you've picked out, I would recommend a lot of starch, and slow, careful sewing. I normally don't cut everything at once. I cut enough for a sample block or two and finish the cutting if I get those assembled correctly. You definitely want sharp blades for your rotary cutter, sharp machine needles, and sharp pins. Please post pictures of your work.
Oh, and welcome to the board!
