Fabric Eraser by Sullivans 

This non-smudge Fabric Eraser easily removes unwanted marks from fabric.

A useful addition to sewing kits, this tool can help wipe pattern traces as well as quilt and appliqué lines.

Use for sewing, quilting, or other general craft projects. Keep it handy for erasing pencil or chalk marks from quilts and fabrics.

Remove markings neatly without leaving any smudges so that your fabric surface stays clean. It does not smear or leave smudges on fabric.

In addition, you can use it to clear drafts of quilt blocks and designs drawn on paper.
