Used a Tube Turner to turn the stem inside out after sewing. A new set of Tube Turner is surprising expensive. I purchased a second hand set from an online auction shop. It is well worth the trouble of getting this tool. It makes the job of making fabric stripe so easy.
Here is my first fabric flower. So pretty, love it.
I use the flower pattern from the Chinese book and follow the flower making instruction from the English book "Fabulous Fabric Flowers". The Chinese book has instruction too, but the English book is much better, clearer and more concise.
