Why a Block of the Month program? There are several reasons to join a BOM program. You get to pay a monthly fee as opposed to having to come up with the full amount at one time. Easier on the budget! You have the opportunity to make a project achievable by only focusing on one month at a time. BOM programs are fabulous for retreats as they are cut and ready to go. No searching through your bins of fabrics! All great reasons to take part in a BOM!
