The Antique pattern Library have published some delightful hand embroidery patterns that are free to use. You will find them listed as E-CL016 Iron-on transfer patterns or simply follow the link
This set of vintage iron-on patterns would be suitable for beginners as most can be worked in stitches such as chain stitch, detached chain and stems stitch. If you are new hand to embroidery here is 12 Surface Stitches for Beginners a PDF file I wrote a while back. These stitches can be applied to these types of patterns. Also check out the first few weeks of TAST for basic stitches and more descriptive tutorials and vintage pattern collectors alike.
These delightful hand embroidery patterns are meant to be used for small items such as pin cushions, doilies, tray cloths, guest towels and the like. There are also a few letters included in the collection. Crazy quilters will find them useful to use in the middle of patches and I can see them interpreted using silk ribbon embroidery or adapted to beading.
These images are a couple of examples from this set of free patterns. They are free, no sign up is required but the Antique Pattern Library are sticklers for you having the latest version of Adobe reader for security reasons. If when you try to open or download a pdf file you receive a message asking for a password you need to upgrade your version of acrobat reader as no passwords are required. If you have problems go to their FAQ page.
