    I have just completed the Floral Design Diploma online and cannot speak highly enough about the course. My tutor Liz was so helpful and encouraging throughout the course and I shall miss waiting for my assignment marks and her helpful comments . Judith’s teaching, in her videos, is so so clear, informative and uncomplicated and I was amazed that in a short time I was capable of creating wonderful arrangements. I look forward to doing many more courses in the school in London – all in all a fantastic experience!

    Online Floral Design Diploma was an excellent and inspirational course. I was able to learn the basic foundations of floristry; especially the flowers and arrangements. Now I look at all sorts of materials in a new perspective and think how I can incorporate them to make a wonderful design! I can highly recommend this course to anyone considering to learn the basics of floristry. The videos were very detailed, with Judith explaining every skill and trick required to make the most of the flowers and make the arrangements look exceptional! There was freedom to be creative with your designs; which I enjoyed the most. Many thanks to Judith Blacklock and her Flower School team for putting together such an exciting and excellent course. I would like to express my sincere thanks to my tutor for being exceptional! Thank you so much for your invaluable advice, guidance and help.
