Working with silk you need a lightweight fusible interfacing, that helps keep the fraying to a minimum and really helps with cutting. A New sharp blade in your cutter also is necessary. I use fine thread and the smallest Sharp needle possible. I love silks but they do take some extra care. Press from the wrong side. I machine embroidered a number of silk blocks for a quilt and they turned out so ( rich) looking. The interfacing is probably the most important thing though!
EPP is English Paper Piecing. It is a hand technique. ( think hexagons/ grandmas flower garden - or check out the Millefiore sew along pictures on Facebook- fabulous! ) I do a lot of EPP but found silks easier to work with by machine ( might just be me). If rotary cutting a new blade also is very important.
If you visit Pinterest or google images and type ( silk quilts) into the search box you will see many, many to inspire you! Beautiful!
