The sewing girls made mug rugs and pillows and chalkboards for their mothers for Christmas presents. Don't they look so cute?
They added pockets to these chalkboards to hold the sponge and chalk.
You can write anything you want on them with chalk and wipe it off with a damp sponge. They just sewed a little bit of elastic to hold the chalk on these ones, by folding the elastic in half and catching it underneath at the same time as they zig zagged the blackboard fabric down all the way around.
This, new to us, fabric was really fun to play around with and I've seen many more applications surfacing on the internet. So If you were wondering about it, I'd say yes, have a go at it. It's fun!
