First, you can print the pattern pieces out as your child grows in sizes!!
I have some really cute Pink Fig patterns that go from size 6m to 5T. Now these patterns cost like $12-$20 bucks each plus shipping. My daughter hits a growth spurt every summer, and I would hate to buy the same pattern every year! So I spend a lot of time tracing out the different sizes before I even use the pattern. This is NO FUN, and I have some really cool patterns that I have not even opened because I am dreading the chore of tracing the sizes out. With PDF patterns I can just save the pattern pieces to a file and when My daughter hits a new size I can just re-print the pattern.
Second is price!
I find PDF patterns on ETSY for as cheap as $3.50, and even if I do spend $12-$15 on a pattern there is no shipping charges and it's good for years so its worth the money
Third, even if your new to sewing you can use one of these patterns easily.
There are lots of pictures in PDF patterns, and the instructions are very detailed. So unlike regular patterns you wont be stuck reading between the lines. And if your like me and you like to jump in before reading the instructions its easy enough to just fallow the pictures.
