First welcome to the forum and good luck in college
Hand embroidery patterns are fairly easy to find. You can use coloring books, old pictures, etc. There are several cross-stitch patterns available free online.
Is there a specific type of embroidery you like? Like blackwork, whitework, redwork, surface embroider, crewel, etc.? Right now I'm favoring cross-stitch, red-, black- and whitework.
