I have been observing that there seems to be an increase in the number of patterns being offered in PDF format. I try to place that in a note at the end of the link so no one is surprised by this. I also open them myself to insure that they are safe and contain a copy of the pattern listed on the link. So far, there has never been a safety or accuracy issue with any of them. I do not expect to have one because most people are honest and upright. Just in case something strange like that ever happens, please be assured that I will not include a link to the pattern on this site. The designer or owner of the web site will also be contacted privately.
Have a great day!
