You know what they are - those wonderful clips found on the top of commercial nursing bras that allow you to unfasten the outer cup of your nursing bra while still ensuring a firm hold on your baby. No one understands what a precious balancing act this is, until they have to try it for themselves. Babies tend to wiggle a lot, and they become more animated when it's time to feed. Lots of so-called "nursing clips require two hands to unfasten them or to hook them up.
Until now. We located one of the best nursing clips on the planet and we've been selling it for many years. This is what the clip looks like.
Any regular bra that has an inner support sling, has both the inner and outer layers held together at the underarm area and the strap area. They normally aren't separate. However, nursing bras have an outer layer made of the fashion fabric, and the inner support layer (the sling) which holds the breast in place when the outer layer is lowered. These two layers need to act independently of one another. The inner sling needs to be fastened to the strap (so it won't fall down) while the outer fabric needs to be lowered, yet be attached to the bra so it can be raised back when the feeding is done. I’ve even seen strap elastic used in place of fabric for the sling.
The clip is made of two parts - a hook art (the upper section) and the tab part (the lower section) Each part appears to have two slots, however the bottom section's upper slot is not a slot, but the tab that fastens to the hook section. The upper part has two slots - the upper, wider slot fastens to the strap, and the lower one attached to the inner sling. The lower section has one slot that fastens to the outer cup.
When drafting the pattern for the outer cup, allow extra on the strap tap length so you can feed it through the slot and sew it down. Likewise for the sling strap extension. The strap width needs to be 3/4" wide - this is the size that fits the nursing clips.
During construction, work on the inner sling separately from the outer cup. The curve at the underarm should first be staystitched with a strip of stabilizer to prevent this area from stretching. Finish with elastic as susual. You will notice that the resulting edge does not have any stretch at all. The inner edge of the sling is not finished at all, or if it is, is overcast with a serger.
The outer cup will have the neckline edge finished as usual. Attach the two cup parts together at the wire line seam (no matter whether you use wires or not. After the cups are sewn into the frame, then you can finish the underarm elastic on the outer cup. You need to have the band attached before you can finish the outer cup underarm edge.
