I did tye-dying with my nephews and nieces yesterday. We went to the local charity shops and picked up white pillow slips and white t.shirts etc. I did a small table cloth. We also had some old calico bags lying around. We were all happy with our results. A lovely fun holiday activity.
I usually do my dying on the stove with a saucepan and boiling water. With the children I used buckets with tap hot water. But the dye was first dissolved in boiling hot water then mixed to the cooler water. The fabric then must be left for longer to soak. I also tried some dye concentrated and in a old squeeze sauce bottle. This was a safe way for kids to dye and a very effective way to get a concentrated colour effect on the garment. I will experiment with this method more.
