Sounds perfect to me, especially since hubby is handling lunch. I meet with three other friends and sew together about every other month at each others houses. 4 is perfect, we all fit around the dining room table. We bring precut projects so it is just sewing. Since you are doing raw edge applique, you may want to set up an additional pattern table or give each of you half a table, like in a class. Most of the raw edge I have done gets quite messy (like scrapbooking) from the expansion of material bits and pieces. One table can be for cutting and assembling the applique and another for sewing.
