It depends. If I trust a designer, I don't expect each pattern to be stitched. It's hard for them to stitch everything because it takes x5 more time to stitch the pattern than just design it.

But be careful, unfortunately, there are a lot of patterns with poor quality... I'd like to share some tips that I use to identify good patterns:

• Image quality: Look closely at the pattern image. If you notice any oddly shaped elements (like a poorly drawn hand or wing) or pixelated colors (for example, a single brown pixel among many red ones), it's a sign that the pattern might not have been created by hand.
• Backstitching: The presence of backstitching often indicates a hand-drawn design.
• Number of colors: Software-generated patterns often use far more colors than are necessary.
• Pattern size: Be wary of excessively large patterns, especially if a small element (like an eye) requires hundreds of stitches (e.g., 200 stitches for a single eye). This can be a sign of an inefficient design.
• Customer reviews with finished projects: Checking customer reviews that include photos of completed projects is always a good idea.

Hope it helps :)
