I've tried a couple of patch Fo's and haven't been at all happy with them. The FO is nothing like the beautiful, deep EO. So I make all my blends with the EO just as Newbie suggested. I always start with a Q-tip, one end dipped in patch and the other end dipped in whatever I want to blend it with and drop it into a zip baggie. I wait an hour or so then adjust the scent based on what I want. I recently did a blend of half patch with half Water Orchid (WSP). I seriously hated it at first because the water orchid was so strong but I decided to give it time. I'm so glad I did! The scents slowly blended and matured so after about a month it's absolutely lovely. Patch blended with any floral is just beautiful so I'm sure you'll be happy with Rose.
Just as an FYI, I've blended patch with 4 different florals. I ended up doing a 50/50 split between the scents, using a total of about 0.7oz ppo. Since both are usually strong scents I go a bit lighter and it's worked well for me. Good luck!
