My suggestion would be to put some of the toys in tubs and if possible store them in another part of the house. Then rotate them out once a week or once a month. Your room will be easier to clean up and less distracting for you and your kids. As soon as the youngest outgrows a toy pass it along to someone else.
Good luck. I hope you can find the time and the enery to continue your crafty life. It is easy to lose yourself in the busyness of motherhood.
