I love Missouri quilt tutorials!
If you are interested in keeping those videos so you can watch them over and over here is the trick:
Example the address of you tube video is:
http://www.youtube.com/watch?v=7DFo-...ayer_embedded#!
just add keep before youtube.com
http://www.keepyoutube.com/watch?v=7...ayer_embedded#!
You will have a warning security pop-up just accept.
Select one of the download options and save to your computer.
Et voila! :-)
Note, the FLV options you will have to download the FLV player Just google it!
Most commun file that will work in most computers is Mp4
AND Mp3 will be use mostly for music videos it will download only the music, or the audio part of the videos.
Have fun!
