I had the same idea as you, as soon as I find a cute sweater I will do that!
I've only felted once, last week, but I think also the importance of a top loading is so you can open it during the cycle to check on your progress, and you CAN'T do that on a front loader. Apparently checking on your progress is pretty important. See my post Recommendations for First Time Felter?
for some input from felters to me.
Also, next time I recommend you post something like this in the How-To Questions forum, you'll get more attention
Welcome to KH, it's wonderful here!!!!!!!!
