I have donted a personalized blanket for the Metro Detroit Mommy Groups 2000 Fan Giveaway going on thru the month of June.  To enter for your chance to win go to http://metrodetroitmommy.blogspot.com/2012/06/2k-giveaway.html?  Good luck!!
I guess an important factor in ordering an item from me would be how long it takes to get your blanket.  To answer that question, right now my turn around time is less than a week.  If this is a last minute gift idea for someone, it is possible!
I realize that I do not have dimensions on the blankets listed on the website ... and I
have a good explanation for that! Each blanket varies based on the material
used! If you are looking for a specific size please do not hesitate to ask! But
to give you a rough estimate on the sizes, my 5 year old uses a stroller size
blanket to sleep with at night (he is a blanket junkie!!!), and it also covers
him fine while watching TV. The TV size blankets would be a better size for
older kids/teens/adults. Recently I just did a TV size blanket as a floor play
blanket for a baby. The size is perfect for that and they can even grow into
them for lap blankets as they get older.

A friend of mine asked me if I could create the stroller blankets in a larger size for her 6 and 4 year old kids to use as TV blankets... if you ask you shall receive!  I have now added them to my collection. 
If you are interested in a custom order, please do not hesitate to ask.  The beauty of the hobby is the endless possibilities!
