I hope they don't discontinue it - they have a really nice variety of fabrics. My only issue with the Collection was when I was trying to get a very specific shade of color but other than that I and many other cosplayers have used those fabrics for a lot of costumes!
2014 Conventions :
Katsucon (Washington, DC) - Megacon (FL) - Colossalcon (OH) - Anime Weekend Atlanta (GA)
Upcoming costumes : Yuffie from Kingdom Hearts, Princess Garnet (coronation gown) from FFIX, and more!
