After a long time of not being happy with the options I had in making E-Patterns available, I have finally cracked it!
Using Adobe Acrobat Reader DC is key. I wrote the recommendation of using it into the instructions accompanying each of my E-Patterns whether you go about printing yourself at home or having the pattern printing by a professional.
You will find my E-Patterns from the 'Catalogue' pull down at the top bar of my site. I have started out with some of the bigger sellers and am adding more nearly each day!
By all means, if there is something you cannot wait for in E-Pattern format, drop me a line and I will add it.
E-Patterns should (but are not guaranteed to) save you from shipping costs and shipping time.
I also recommend using lightweight paper whether in letter (A4) or large format size for translucency and ease of cutting.
